+## Release Process
+
+### Creating a Release
+
+1. **Update CHANGELOG.md** with the new version and changes
+2. **Create a git tag** for the version:
+   ```bash
+   git tag -a v1.0.0 -m "Release v1.0.0"
+   git push origin v1.0.0
+   ```
+3. **GitHub Actions will automatically**:
+   - Build binaries for all platforms
+   - Create SHA256 checksums
+   - Generate SBOM
+   - Create GitHub Release with assets
+
+### Manual Release
+
+For manual releases or testing:
+
+```bash
+# Trigger workflow manually
+gh workflow run release.yml -f tag=v1.0.0
+
+# Or create tag and push
+git tag -a v1.0.0 -m "Release v1.0.0"
+git push origin v1.0.0
+```
+
+### Platform Support
+

+# Contributing to El Foundation
+
+## One Task = One Branch = One Owner
+
+Every issue gets its own branch. Branch names follow this pattern:
+
+```
+owner-identifier/short-description
+```
+
+Examples:
+- `cto/ELF-15-hatch-stack-migration`
+- `engineer/hatch-bootstrap`
+- `engineer/hatch-storage`
+
+## No Direct Commits to `main`
+
+All changes go through a pull request. No exceptions.
+
+## Pull Request Process
+
+**Important:** Only the CEO or CTO can merge pull requests. See [PR Submission Guidelines](docs/engineering/pr-submission-guidelines.md) for full details.
+
+1. **Open a PR** from your branch to `main`.
+2. **Fill out the PR template** (risk, rollback, verification).
+3. **Request review** from the relevant owner:
+   - Code changes → another engineer or CTO
+   - UX-facing changes → UXDesigner
+   - Security-sensitive changes → SecurityEngineer
+4. **Address feedback** or escalate disagreements in writing.
+5. **Wait for merge** — only CEO or CTO can merge your PR.
+6. **Tag for merge** — comment on your PR: `@AlexChen or @JordanPatel - PR approved, ready for merge`
+
+## Commit Messages
+
+Commit messages explain **why**, not what. The diff shows what changed; the message explains the reasoning.
+
+Good:
+```
+Add rotating refresh tokens
+
+Using a rotating refresh token strategy prevents replay attacks
+and gives us a clean theft-detection signal. See ADR-0003.
+```
+
+Bad:
+```
+Update auth.ts
+```
+
+## Code Style
+
+- **Go, idiomatic.** `gofmt` clean, `go vet ./...` clean. Prefer the standard library over new dependencies. Reach for a third-party package only when stdlib genuinely does not cover the need.
+- **Pure logic in `internal/`, I/O in adapters.** Business logic does not call `http.*` or `database/sql` directly. Storage and HTTP are replaced with interfaces in tests.
+- **Server-rendered by default.** Reach for client JS or a SPA only when the component genuinely needs state, effects, or live updates. The v0.1 web UI is HTML templates plus a small vanilla-JS SSE client.
+- **Keep packages small.** Prefer small, focused packages over clever abstractions. One file per route group in `internal/handler/`.
+- **No comments unless the code is genuinely non-obvious** or there is a real `// FIXME`. Let the code explain itself; let the commit message explain the *why*.
+- **No defensive error handling around things that should not fail.** Let it panic or return the error. Wrap at the boundary, not at every call site.
+
+## Definition of Done
+
+A task is not done until **all** of the following are true:
+
+1. Code is written and reviewed.
+2. Tests pass. `go test ./...` is green. CI is green.
+3. Documentation is updated (`docs/engineering/` or `docs/adrs/` as appropriate).
+4. No secrets in plain text.
+5. User-facing changes are validated.
+6. Rollback path is known.
+7. Handoff is clean — follow-up work is captured in a new issue.
+
+## Security
+
+- Never commit secrets, credentials, or customer data.
+- Security-sensitive changes (auth, crypto, secrets, permissions) require SecurityEngineer review before merging.
+- Report vulnerabilities to the CTO immediately.
+
+## Questions?
+
+Open an issue or ask in the project channel. Async-first: write it down.

+# Hatch Landing Page — Deployment Guide
+
+## Overview
+
+The Hatch landing page (`hatch.surf`) is a **static HTML** site deployed via **Docker** on the production server.
+
+**Key principle**: All changes MUST go through the git repository and automated deployment. Never edit files directly on the server or use `/var/www`.
+
+---
+
+## Repository
+
+**Location**: `/home/nara/apps/web/`
+
+**Git Remotes**:
+- `github` → `elfoundation/hatch` (source of truth)
+- `origin` → `el-foundation/hatch-surf` (Gitea push-mirror, deploys to hatch.surf)
+
+**Structure**:
+```
+site/                   # Static files served by nginx
+  index.html            # Main landing page
+  style.css             # Styles
+  main.js               # Anime.js animations
+Dockerfile              # Docker build configuration (static files only)
+docker-compose.yml      # Container orchestration
+deploy.sh               # Deployment script
+```
+
+---
+
+## Deployment Flow
+
+### Source of Truth
+
+**GitHub `main`** is the source of truth. Gitea is a push-mirror.
+
+All development happens via PRs to `elfoundation/hatch`. The deploy script pulls from GitHub and pushes to Gitea.
+
+### Automatic (Recommended)
+
+1. Merge PR to GitHub `main`
+2. Gitea webhook triggers `gitea-webhook.py`
+3. Script runs `deploy.sh` automatically
+4. `deploy.sh` pulls from GitHub, pushes to Gitea (push-mirror), rebuilds Docker, restarts
+
+### Manual
+
+```bash
+cd /home/nara/apps/web
+./deploy.sh
+```
+
+**What `deploy.sh` does**:
+1. `git pull github main` — fetches latest from GitHub (source of truth)
+2. `git push origin main` — syncs to Gitea (push-mirror)
+3. `cd site && docker build -t hatch-web:latest .` — rebuilds image
+4. Stops and removes old container
+5. `docker run -d` — starts new container
+6. Verifies deployment with health check
+
+---
+
+## Docker Setup
+
+**Container**: `hatch-web`  
+**Port**: `8080` (mapped to host)  
+**Internal**: nginx serving static files on port 80  
+**Network**: `hatch-network`
+
+**Check status**:
+```bash
+docker ps | grep hatch-web
+docker logs hatch-web
+```
+
+**Restart without rebuild**:
+```bash
+docker compose -f /home/nara/apps/web/docker-compose.yml restart
+```
+
+---
+
+## Making Changes
+
+### 1. Edit the static files
+
+```bash
+cd /home/nara/apps/web
+
+# Edit landing page
+vim out/index.html
+
+# Edit styles
+vim out/style.css
+
+# Edit animations
+vim out/main.js
+```
+
+### 2. Test locally (optional)
+
+```bash
+# Serve files locally
+cd out && python3 -m http.server 3000
+# Visit http://localhost:3000
+```
+
+### 3. Commit and push
+
+```bash
+git add .
+git commit -m "Description of changes"
+git push origin main
+```
+
+### 4. Deploy
+
+Either wait for webhook or run manually:
+```bash
+./deploy.sh
+```
+
+### 5. Verify
+
+```bash
+curl -s http://localhost:8080 | head -20
+# Or visit https://hatch.surf
+```
+
+---
+
+## Common Mistakes to Avoid
+
+❌ **DON'T**: Edit files in `/var/www/html/`  
+❌ **DON'T**: Edit files directly inside the Docker container  
+❌ **DON'T**: Work on static HTML/CSS files in a workspace without committing  
+❌ **DON'T**: Copy files to the server without using git  
+
+✅ **DO**: Edit files in `/home/nara/apps/web/out/`  
+✅ **DO**: Commit changes to git  
+✅ **DO**: Use `deploy.sh` for deployment  
+✅ **DO**: Test locally before pushing  
+
+---
+
+## Rollback
+
+If a deployment causes issues:
+
+```bash
+cd /home/nara/apps/web
+
+# View recent commits
+git log --oneline -10
+
+# Revert to previous version
+git revert HEAD
+git push origin main
+
+# Redeploy
+./deploy.sh
+```
+
+Previous builds are backed up in `out.backup.*` directories.
+
+---
+
+## Cache Headers
+
+**HTML pages**: `no-cache, must-revalidate` — browsers always revalidate, ensuring fresh content after deploys.
+
+**Static assets** (CSS/JS/images): `public, immutable` with 1-year expiry.
+
+**Nginx config**: Built into the Dockerfile.
+
+If users report seeing old content after deployment:
+1. Verify the container is running: `docker ps | grep hatch-web`
+2. Check the HTML has new content: `curl -s http://localhost:8080 | head -5`
+3. Ask user to hard refresh: Ctrl+Shift+R (Chrome/Firefox) or Cmd+Shift+R (Mac)
+
+---
+
+## Troubleshooting
+
+**Container not starting**:
+```bash
+docker logs hatch-web
+docker compose -f /home/nara/apps/web/docker-compose.yml up -d
+```
+
+**Changes not showing**:
+1. Verify commit pushed: `git log --oneline -1`
+2. Check container was rebuilt: `docker images | grep hatch-web`
+3. Force rebuild: `cd /home/nara/apps/web && docker build -t hatch-web:latest . && docker compose up -d`
+
+**Port conflict**:
+```bash
+lsof -i :8080
+# Kill conflicting process or change port in docker-compose.yml
+```

+
+## Hatch — Deploy in one command
+
+Hatch is a self-hostable HTTP request inspector + mocker. Ship it to any VPS with Docker.
+
+**[Read why we are building Hatch →](https://hatch.sh/blog/why-we-are-building-hatch)**
+
+### Quick start (local dev, no HTTPS)
+
+```bash
+docker compose up --build
+# Hatch UI: http://localhost:8080
+# Health check: http://localhost:8080/healthz
+```
+
+Or run the binary directly:
+
+```bash
+go run ./cmd/hatch
+# Health check: http://localhost:8080/healthz
+```
+
+### Production (with HTTPS via Caddy)
+
+```bash
+# Set your domain name
+cp .env.example .env
+# Edit HATCH_HOSTNAME in .env to your real domain
+
+# Start Hatch + Caddy (auto-issues Let's Encrypt cert)
+docker compose --profile with-caddy up -d --build
+# Hatch UI: https://{your-domain}
+# Capture endpoint: https://{your-domain}/{endpoint-id}
+```
+
+### Architecture
+
+```
+Internet → :443 (Caddy) → hatch:8080 (Go binary, internal network)
+                 │
+                 ├─ Auto TLS (Let's Encrypt, or self-signed for localhost)
+                 ├─ Reverse proxy with security headers
+                 └─ JSON access logs to stdout
+```
+
+Caddy terminates TLS and reverse-proxies to the Hatch Go binary. The Hatch container only listens on `127.0.0.1:8080` — it's never directly exposed to the internet.
+
+## CLI Reference
+
+Hatch includes a powerful CLI for interacting with the server from the command line:
+
+```bash
+# Capture requests
+hatch capture https://api.example.com/webhook
+
+# Inspect captured traffic
+hatch inspect my-webhook
+
+# Search for specific requests
+hatch search my-webhook -query 'status:500'
+
+# Replay requests to other services
+hatch replay <request-id> -endpoint my-webhook -target https://httpbin.org/post
+
+# Configure mock responses
+hatch mock set my-webhook -status 200 -body '{"ok":true}'
+
+# Generate OpenAPI documentation
+hatch doc generate my-webhook > openapi.json
+```
+
+For detailed CLI documentation, see [docs/engineering/cli.md](docs/engineering/cli.md).
+
+## Technology Stack
+
+See [docs/engineering/tech-stack.md](docs/engineering/tech-stack.md) for current choices and rationale, and [docs/adrs/](docs/adrs/) for the decision records that produced them.

+# Hatch.surf Architecture
+
+## Overview
+
+Hatch.surf is the landing page and brand site for El Foundation. It consists of:
+- **Static frontend** (site/) — HTML/CSS/JS served via nginx
+- **Go backend** (cmd/hatch) — API server for future dynamic features
+
+## Deployment Architecture
+
+```
+GitHub Push → GitHub Actions → Build Docker Image → SCP to Server → Docker Run → Caddy (reverse proxy)
+```
+
+**Benefits:**
+- Containerized — isolated from host
+- Reproducible — same image in dev/prod
+- No host filesystem dependency (no `/var/www`)
+- Easy rollback — just change image tag
+- Self-contained — static files baked into image
+
+## Docker Setup
+
+### Frontend (site/)
+
+**Dockerfile:**
+```dockerfile
+FROM nginx:alpine
+RUN rm -rf /usr/share/nginx/html/*
+COPY . /usr/share/nginx/html/
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
+
+**docker-compose.yml:**
+```yaml
+services:
+  hatch-homepage:
+    build: .
+    ports:
+      - "3000:80"
+    restart: unless-stopped
+```
+
+Note: Static files are baked into the image during build. No host mount required.
+
+### Backend (cmd/hatch)
+
+**Dockerfile:**
+```dockerfile
+FROM golang:1.25-alpine AS build
+WORKDIR /src
+COPY go.mod go.sum ./
+RUN go mod download
+COPY . ./
+RUN CGO_ENABLED=0 GOOS=linux go build -ldflags="-s -w" -o /bin/hatch ./cmd/hatch
+
+FROM scratch
+COPY --from=build /bin/hatch /bin/hatch
+EXPOSE 8080
+ENTRYPOINT ["/bin/hatch"]
+```
+
+**docker-compose.yml:**
+```yaml
+services:
+  hatch:
+    build: .
+    restart: unless-stopped
+    ports:
+      - "127.0.0.1:8080:8080"
+    volumes:
+      - hatch-data:/data
+    environment:
+      - HATCH_PORT=8080
+      - HATCH_DB_PATH=/data/hatch.db
+      - HATCH_BASE_URL=${HATCH_BASE_URL:-http://localhost}
+
+  caddy:
+    image: caddy:2-alpine
+    restart: unless-stopped
+    ports:
+      - "80:80"
+      - "443:443"
+    volumes:
+      - ./Caddyfile:/etc/caddy/Caddyfile:ro
+      - caddy-data:/data
+      - caddy-config:/config
+    environment:
+      - HATCH_HOSTNAME=${HATCH_HOSTNAME:-localhost}
+    profiles:
+      - with-caddy
+
+volumes:
+  hatch-data:
+  caddy-data:
+  caddy-config:
+```
+
+## Deployment Flow
+
+### GitHub Actions (deploy-site.yml)
+
+1. **Build** — `docker build -t hatch-homepage:latest ./site`
+2. **Save** — `docker save hatch-homepage:latest | gzip > hatch-homepage.tar.gz`
+3. **SCP** — Copy tarball to server
+4. **Load** — `docker load < /tmp/hatch-homepage.tar.gz`
+5. **Run** — `docker run -d --name hatch-homepage ...`
+
+### Server Configuration
+
+**Nginx reverse proxy** (host nginx):
+```nginx
+server {
+    listen 80;
+    server_name hatch.surf;
+    return 301 https://$host$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name hatch.surf;
+
+    ssl_certificate /etc/letsencrypt/live/hatch.surf/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/hatch.surf/privkey.pem;
+
+    location / {
+        proxy_pass http://127.0.0.1:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+## Secrets Management
+
+- **DEPLOY_HOST** — Server IP/hostname
+- **DEPLOY_USER** — SSH user (nara)
+- **DEPLOY_KEY** — SSH private key (stored in GitHub Secrets)
+
+No secrets in repo. All deployment credentials in GitHub Secrets.
+
+## Rollback Procedure
+
+If deployment fails:
+```bash
+# On server
+docker stop hatch-homepage
+docker rm hatch-homepage
+docker run -d --name hatch-homepage --restart unless-stopped -p 127.0.0.1:3000:80 hatch-homepage:previous-tag
+```
+
+## Future Improvements
+
+1. **Container registry** — Push images to GitHub Container Registry (ghcr.io)
+2. **Health checks** — Add HEALTHCHECK to Dockerfile
+3. **Monitoring** — Add Prometheus metrics endpoint
+4. **CDN** — Serve static assets via Cloudflare/CloudFront
+5. **SSL automation** — Certbot in container or Caddy auto-SSL

+# ADR-0002: Hatch detail stack
+
+- Status: Accepted
+- Date: 2026-06-22
+- Authors: CTO
+- Supersedes: none
+- Related: [ADR-0001](https://github.com/elfoundation/hatch/blob/main/docs/adrs/0001-stack.md), [Hatch v0.1 plan (ELF-13)](https://github.com/elfoundation/hatch/issues/13)
+
+## Context
+
+[ADR-0001](https://github.com/elfoundation/hatch/blob/main/docs/adrs/0001-stack.md) fixed the v0.1 stack at the level of "Go + SQLite + stdlib `net/http` + server-rendered HTML + SSE + single Docker image." That ADR deliberately did not pick:
+
+- which HTTP router (stdlib `net/http` with method-based mux vs. a third-party router)
+- which SQLite driver
+- which templating system (only said "server-rendered HTML")
+- which test framework
+- which license
+
+This ADR closes those gaps with concrete choices, named alternatives, and the rollback path for each.
+
+## Decision
+
+| Concern | Choice | One-line reason |
+|---|---|---|
+| HTTP router | `go-chi/chi` (v5) for v0.1 | SSE middleware story is cleaner than hand-rolled on `http.ServeMux`; chi is the lightest router that still gives us real middleware composition. |
+| SQLite driver | `modernc.org/sqlite` (pure Go) | Keeps the "no CGO" promise that the static-binary distribution rests on. |
+| Templates | stdlib `html/template`, embedded with `//go:embed` | Auto-escaping by default, no template-engine dependency, no runtime parsing of the filesystem. |
+| Test framework | stdlib `testing` + `net/http/httptest` | No assertion library unless pain demands one. |
+| License | MIT (revised; was Apache-2.0) | Permissive, lowest friction for small single-binary dev tools; CEO decision [ELF-141](https://github.com/elfoundation/hatch/issues/141). |
+| Config | Environment variables only (`PORT`, `HATCH_DB_PATH`, `HATCH_LISTEN`) | Twelve-factor. No YAML/JSON config files for v0.1. |
+| Logging | stdlib `log` to stdout, structured via `slog` (Go 1.21+) | No third-party logging library until we need log shipping. |
+| Process model | Single process, one port, in-process SSE hub | v0.1 is a self-hosted single-binary product. No workers, no sidecars. |
+
+### Router: `go-chi/chi`
+
+Chi v5 is the smallest router that still composes well. It sits on top of `http.Handler`, so it does not break the stdlib-first principle — it just gives us `r.Use(middleware.Logger)`, `r.Route("/e/{id}", func(r chi.Router) { ... })`, and a clean SSE middleware (`middleware.Flush`).
+
+**Why not stdlib `net/http` only?** Go 1.22 added method-based routing and path parameters to `http.ServeMux`. For v0.1's surface (~6 routes) it is genuinely enough. We adopt chi for two reasons: (1) the SSE middleware in `chi/middleware` is one line vs. ~20 lines of hand-rolled flush-on-write logic, and (2) the moment we add a second cross-cutting concern (request ID, auth-ready, rate limit) the hand-rolled composition gets ugly fast.
+
+**Reversibility.** Drop-in: chi is an `http.Handler`. Reverting to stdlib `ServeMux` is a one-file change to `cmd/hatch/main.go`. The handler layer is router-agnostic by construction.
+
+### SQLite driver: `modernc.org/sqlite`
+
+Pure Go. Translates SQLite's C source via `ccgo` at build time, so the produced driver is a normal Go package with no `cgo` import.
+
+**Why not `mattn/go-sqlite3`?** It is the most popular SQLite driver, but it requires CGO. CGO forces us to either (a) ship a glibc-linked binary that breaks on musl-based images, or (b) maintain a separate CGO build pipeline. Both are paid complexity for a feature (a C compiler in CI) we do not otherwise need.
+
+**Why not the stdlib `database/sql` only?** The `database/sql` package is the API; it is not a driver. We still need a driver, and we still need migrations, and we still need a `Repository` interface above it. The choice here is the driver.
+
+### Templates: stdlib `html/template`, `//go:embed`-ed
+
+`html/template` auto-escapes context-sensitively (HTML, JS, URL, CSS contexts). It is in the standard library, has no dependencies, and produces no runtime surprises. We embed templates at build time with `//go:embed templates/*.html` so the binary is self-contained and there is no filesystem layout to manage at deploy time.
+
+**Why not `templ` or `jet`?** Both add a build step (`templ generate`) to the dev loop. The v0.1 surface is small enough that a hand-rolled `{{range .Requests}}` is not a liability. We will revisit if template churn becomes a real cost.
+
+### Test framework: stdlib `testing` + `net/http/httptest`
+
+`testing` is in the standard library, plays well with `go test`, and is what every Go engineer already knows. `httptest` gives us `httptest.NewRecorder` for handler unit tests and `httptest.NewServer` for end-to-end smoke tests without a real network socket.
+
+**Why not `testify` or `gocheck`?** No assertion library has yet earned its place. We will adopt one when the boilerplate of `if got != want { t.Errorf(...) }` becomes a real cost, not before.
+
+### License: MIT (revised 2026-06-23)
+
+**Superseded by CEO decision** — [ELF-141](https://github.com/elfoundation/hatch/issues/141) locked the OSS license at **MIT** ahead of the v0.1 public launch. The original Apache-2.0 reasoning is preserved below for history; the repo now ships under MIT (see [`LICENSE`](../../LICENSE)). MIT→Apache-2.0 remains a compatible, reversible upgrade if a corporate contributor raises patent concerns later.
+
+#### Original Apache-2.0 reasoning (superseded)
+
+Permissive. Explicit patent grant. Matches what the Go ecosystem uses (Kubernetes, Docker, the Go toolchain itself are permissive-licensed). Compatible with corporate adoption without legal-review friction.
+
+**Why not MIT?** MIT is also acceptable, but the patent grant in Apache-2.0 is a real protection for downstream contributors and is a default in our target ecosystem.
+
+## Consequences
+
+### Positive
+
+- The full v0.1 dependency surface is: `go-chi/chi`, `modernc.org/sqlite`, and `github.com/google/uuid` (if we use it for endpoint IDs). Everything else is stdlib. That is a small, reviewable surface.
+- The single-binary distribution story holds: `CGO_ENABLED=0 go build` produces a working static binary, and the Docker build ends in `scratch` with no runtime.
+- The license, the test framework, and the template engine are all things an incoming Go engineer already knows. Zero ramp cost on tooling.
+- Each choice has a one-day-or-less reversal path. The stack is composable from independent parts; nothing in this ADR forces a bigger rewrite to undo.
+
+### Negative / Risks
+
+- Chi is one more dependency to track. If a future Go stdlib release subsumes the middleware story, we have a small migration.
+- `modernc.org/sqlite` is slower than the C version on raw throughput benchmarks (~2–3× on simple SELECTs). For v0.1's workload (a self-hosted single-user product) this is invisible. We will measure before optimizing.
+- Stdlib `html/template` has no inheritance, no partials-with-arguments, and no "components." If template complexity grows, we will feel it. The mitigation is to keep the page count low (Capture page, Inspect page, Mock config page, error page).
+- (Historical, pre-MIT switch:) Apache-2.0 is more verbose than MIT. Trivial cost; mentioned for completeness.
+
+## Alternatives Considered
+
+### Option A: `net/http` only (no chi)
+
+- Pros: zero router dependency; one fewer thing to upgrade; Go 1.22's `ServeMux` is genuinely good.
+- Cons: SSE flush middleware is hand-rolled; auth/cors/rate-limit middleware are also hand-rolled; the cost of NOT having middleware composition grows with every new cross-cutting concern.
+- Why rejected: SSE is in v0.1 (Inspect live). The first place we will want a second middleware is auth, even if auth itself ships later. Paying for chi now is cheaper than paying for hand-rolled composition later.
+
+### Option B: `mattn/go-sqlite3`
+
+- Pros: most popular SQLite driver, fast, well-known.
+- Cons: requires CGO. Breaks the static-binary promise or forces a second build pipeline.
+- Why rejected: the cost of CGO exceeds the value of `mattn`'s ecosystem familiarity.
+
+### Option C: `templ` for templates
+
+- Pros: type-safe templates, IDE autocompletion, components.
+- Cons: requires a code-generation step (`templ generate`) on every save. The dev loop slows down. The runtime feature set is ~equivalent to `html/template` for our surface.
+- Why rejected: the v0.1 template surface is small enough that hand-written `html/template` is not yet a liability. We can adopt `templ` later if template churn becomes a real cost.
+
+### Option D: MIT license
+
+- Pros: shorter, more familiar to individual contributors.
+- Cons: no explicit patent grant.
+- Why rejected: Apache-2.0's patent grant is a real downstream protection and matches our target ecosystem. The longer license header is a trivial cost.
+
+## Rollback Plan
+
+| Choice | Rollback |
+|---|---|
+| `go-chi/chi` | Replace `chi.Router` with `http.ServeMux` in `cmd/hatch/main.go`. Handlers and store are unchanged. ~half a day. |
+| `modernc.org/sqlite` | Swap to `mattn/go-sqlite3`. Add CGO to the Dockerfile. Update CI to install `gcc`. ~half a day, plus the Dockerfile/CI change. |
+| `html/template` | Adopt `templ` (or `jet`). Adds a code-generation step. ~1 day plus regen. |
+| stdlib `testing` | Adopt `testify`. Mechanical import swap. ~2 hours. |
+| MIT (was Apache-2.0) | Relicense with contributor agreement. Not a code change, but a legal process. MIT→Apache-2.0 is a compatible upgrade if patent concerns arise. |
+| Env-only config | Adopt `viper` or `koanf`. ~1 day including flag plumbing. |
+
+The first five rollbacks are independent and can be done in any order. The license change is not ours to make unilaterally.

+## What goes where
+
+| Surface                                  | Use                              | File                                   |
+| ---------------------------------------- | -------------------------------- | -------------------------------------- |
+| Favicon (browser tab, GitHub avatar)     | The **mark**, not the wordmark   | `brand/favicon/favicon.ico`            |
+| Apple touch icon / PWA icon               | The mark, 512px                  | `brand/favicon/favicon-512.png`        |
+| README header                            | The **wordmark** (200x60+)       | `brand/wordmark/wordmark-200x60.png`   |
+| GitHub social preview / blog / link card | The **OG image** (1200x630)      | `brand/og/og.png`                      |
+| Big surfaces, slides, README top         | The **README banner** (1280x640) | `brand/banner/readme-banner.png`       |
+
+For the favicon, always use `mark.svg` or one of the favicon PNGs — never the full
+wordmark. The wordmark does not read at 16x16.
+
+## Clear space
+
+Treat the mark as a square and the wordmark as the mark + the word. Clear space
+is **1× the cap-height of the "h" in "hatch"** on every side.
+
+- Wordmark: at least one "h"-height of empty space on top, bottom, left, and right
+- Mark: at least one "h"-height on every side
+
+```
+   ┌──────────────────────────────┐
+   │                              │  ← 1× clear space
+   │   ┌──┐  hatch                │
+   │   │  │                       │
+   │   └──┘                       │
+   │                              │  ← 1× clear space
+   └──────────────────────────────┘
+```
+
+## Minimum size
+
+- Wordmark: **120px wide** is the minimum. Below that, switch to the mark.
+- Mark: **16px** is the minimum (we ship a tuned 16px favicon).
+
+## Color
+
+The brand has **one active color, one neutral, and one accent**. That's it.
+
+| Token    | Hex       | Use                                               |
+| -------- | --------- | ------------------------------------------------- |
+| Ink      | `#0A0A0B` | Wordmark, primary type, dark surfaces             |
+| Paper    | `#FAFAF9` | Light surfaces, type on dark                      |
+| Accent   | `#F59E0B` | The "captured" signal — one place per composition |
+
+Neutral scale (for docs and UIs, not the wordmark): `#71717A` `#A1A1AA` `#D4D4D8` `#E4E4E7` `#F4F4F5`.
+
+**Don't pick colors outside the kit.** If you need another color, ask the Head of
+Marketing; do not invent one.
+
+## Light and dark mode
+
+The wordmark and the mark are **single-color**. Pick the right variant for the
+surface — never change the color of the wordmark to fit a theme.
+
+- **On a light surface** (≥ 4.5:1 contrast): use `wordmark.svg` (ink) or `mark.svg`
+- **On a dark surface**: use `wordmark-dark.svg` (paper) or `mark-dark.svg`
+- **Need a background tile?** Use `wordmark-on-light.svg` or `wordmark-on-dark.svg`
+
+For GitHub READMEs, GitHub auto-switches images in dark mode only if you use
+the `#gh-dark-mode-only` / `#gh-light-mode-only` MediaFragments trick:
+
+```markdown
+<picture>
+  <source media="(prefers-color-scheme: dark)" srcset="brand/wordmark/wordmark-dark.svg">
+  <img src="brand/wordmark/wordmark.svg" alt="Hatch" width="200">
+</picture>
+```
+
+## Typography (display + body)
+
+The wordmark uses **Inter Bold**. The brand voice guide and READMEs use:
+
+- **Display / headings:** Inter (Bold or SemiBold)
+- **Code / mono:** JetBrains Mono (Regular or Medium)
+
+Both are OFL-licensed and on the system. Don't substitute a different sans or mono
+in brand surfaces without sign-off.
+
+## Do not
+
+- **Don't stretch.** Always use the mark/wordmark at its native aspect ratio. If
+  you need it bigger, scale proportionally.
+- **Don't recolor.** The wordmark is ink or paper — period. No brand-color,
+  gradient, rainbow, or AI-painted versions.
+- **Don't add effects.** No drop shadows, no glows, no outlines, no bevel, no
+  inner shadows. The mark is a flat shape.
+- **Don't rotate.** The hatch opens at the top. Don't tilt the mark.
+- **Don't rearrange the wordmark.** The mark always sits to the **left** of the
+  wordmark, with a 0.22×-mark-width gap. No stacking, no right-alignment.
+- **Don't put the wordmark on a busy image.** The wordmark needs contrast. On a
+  photo or a complex background, use a solid color tile behind it.
+- **Don't use the wordmark in body copy.** The wordmark is for headers, banners,
+  and brand surfaces only. Body type stays in Inter.
+- **Don't use the favicon as a profile picture.** Use the 512px PNG (`mark-512.png`)
+  for that, and round the corners if you want — but the square mark is the
+  canonical shape.
+
+## Licensing & attribution
+
+- **Inter** — SIL Open Font License 1.1 (Inter by Rasmus Andersson, rsms.me)
+- **JetBrains Mono** — SIL Open Font License 1.1 (JetBrains)
+- The mark and wordmark are the property of El Foundation. Use them to talk about
+  Hatch. Do not register them as a trademark or use them to sell a competing
+  product.
+
+## Need something new?
+
+If a new surface needs a brand asset that isn't in the kit (a slide template, a
+business card, a T-shirt, an icon variant), open an issue assigned to the Brand
+Designer. Do not stretch, recolor, or rearrange this kit to make it work.

+# Company Charter
+
+## Mission
+
+Build institutions that outlast their founders. We exist to create technology and organizations that compound in value over time, not to chase trends or optimize for short-term outcomes. Every product we ship and every process we design must make the next version of the company stronger than the last.
+
+## Vision
+
+A world where the best teams operate with radical clarity: everyone knows why their work matters, decisions are made on evidence rather than authority, and the institution keeps improving even as people join and leave. We will be the company other companies study when they ask, "How did they build that?"
+
+## Operating Principles
+
+1. **Source of truth is the repo, not memory.**
+   If it is not written down, committed, and linkable, it does not exist. Decisions, plans, and context live in durable documents, not Slack threads or someone's head. This is how we scale without decay.
+
+2. **Optimize for reversibility.**
+   Move fast on two-way doors; slow down on one-way doors. Default to experiments with clear rollback paths. A decision without a cost of reversal is a bet, and bets require higher evidence bars.
+
+3. **Disagree and commit, but write it down.**
+   Dissent is healthy. Once a decision is made, everyone commits fully. The minority opinion is archived with its reasoning so we can revisit it if the decision proves wrong. No invisible reservations.
+
+4. **Hire for slope, not intercept.**
+   We prefer people who learn fast over people who know everything today. The problems we will face in two years do not exist yet; we need teams that can grow into them.
+
+5. **Protect focus ruthlessly.**
+   Saying no is a core competency. We maintain a short, ordered priority list and decline everything else. Multitasking is organizational debt.
+
+6. **Pull for bad news.**
+   If problems stop surfacing, we have lost our information edge. Every manager's job includes creating conditions where the worst news travels fastest.

+# How We Decide
+
+Every major decision at this company goes through the same process. A "major decision" is anything that:
+
+- Commits the company to a path that is hard or expensive to reverse
+- Affects more than one team or function
+- Costs more than $2,000 or $500/month recurring
+- Changes how we work (process, tools, org structure)
+- Introduces new security, legal, or compliance exposure
+
+If it is not major, the owner decides and documents. Do not slow down small decisions.
+
+## The Process
+
+### 1. Frame the decision
+
+Write a one-page decision brief that includes:
+
+- **Question:** What exactly are we deciding?
+- **Context:** Why now? What changed?
+- **Options:** At least two real alternatives, including "do nothing."
+- **Criteria:** 3-5 criteria we will use to judge the options.
+- **Recommendation:** The owner's preferred option and why.
+- **Risks:** What could go wrong? How would we know?
+- **Rollback plan:** If we choose wrong, how do we undo it?
+
+### 2. Gather advice
+
+The owner shares the brief with all stakeholders and gives them 24-48 hours to comment in writing. Stakeholders are expected to:
+
+- Raise concerns they can support with evidence
+- Suggest alternatives or mitigations
+- Declare if they have a conflict of interest
+
+The owner does not need to incorporate every piece of advice. The goal is to surface blind spots.
+
+### 3. Decide
+
+The decision owner makes the call. The owner is:
+
+- The relevant department lead for functional decisions
+- The CEO for cross-functional or high-stakes decisions
+- The board for capital, major partnerships, or existential bets
+
+The owner writes the decision in a durable document (issue comment, PR description, or committed file) and archives the brief alongside it.
+
+### 4. Communicate
+
+The owner announces the decision to all affected parties within 24 hours. The announcement includes:
+
+- What was decided
+- Why (with a link to the decision record)
+- What changes for whom
+- When the decision takes effect
+- How to raise new information that might change the outcome
+
+### 5. Review
+
+Major decisions are revisited on a schedule:
+
+- **30-day check:** Did the expected outcome materialize? Any early warning signs?
+- **90-day review:** Was the decision correct? What did we learn?
+- **Annual audit:** Which decisions should we reverse or update?
+
+The owner of the original decision is responsible for scheduling these reviews.
+
+## Decision Criteria
+
+We evaluate options against these criteria, weighted by the specific decision:
+
+1. **Reversibility:** Can we undo this cheaply? Higher weight for one-way doors.
+2. **Evidence quality:** How strong is the supporting data? Higher weight for novel or risky bets.
+3. **Optionality:** Does this close off future paths or keep them open?
+4. **Execution cost:** Time, money, and opportunity cost.
+5. **Alignment:** How well does this fit our charter and operating principles?
+
+## Who Signs Off
+
+| Decision tier | Decision owner | Required sign-off |
+|---|---|---|
+| Functional (affects one team) | Department lead | None; document and notify |
+| Cross-functional (affects multiple teams) | CEO | Department leads consulted |
+| High-stakes (irreversible, expensive, existential) | CEO | Board approval required |
+| Security / legal / compliance | SecurityEngineer or Ops | CEO must be informed |
+
+## Anti-Patterns
+
+- **Consensus theater.** If everyone must agree, no one decides. We optimize for speed and clarity, not universal comfort.
+- **Analysis paralysis.** Two good options with similar expected value? Pick one and ship. The cost of deliberation often exceeds the cost of being slightly wrong.
+- **Decisions without owners.** Every decision has a single named owner. No committees.
+- **Invisible reversals.** If we change our mind, we write a new decision record. No ghosting past decisions.

+# Operating Model
+
+## Decision Rights
+
+We run a **advice-and-decide** model, not consensus.
+
+- **The owner decides.** Every initiative has a single named owner. That owner gathers input, makes the call, and owns the outcome. No design-by-committee.
+- **The owner writes the decision record.** Every significant decision gets a one-paragraph rationale committed to the relevant issue or document.
+- **Escalation is a feature, not a failure.** If an owner is stuck, blocked, or faces a one-way door they are uncomfortable opening alone, they escalate to their manager with a clear recommendation, not a question.
+
+### Authority Matrix
+
+| Decision type | Owner | Escalation path |
+|---|---|---|
+| Product feature priority | Product lead | CEO |
+| Technical architecture | CTO | CEO |
+| Design system changes | UXDesigner | CTO |
+| Marketing message / channel | CMO | CEO |
+| Hiring / firing | Department lead | CEO |
+| Budget > $500/mo or one-time > $2,000 | CEO | Board |
+| Security policy, auth, secrets | SecurityEngineer | CTO → CEO |
+| Skill / agent governance | CEO | Board |
+
+## Work Ownership
+
+- **One task = one owner = one branch.** No shared ownership. If a task is too big for one person, split it.
+- **Tasks are tracked in a structured workflow.** Backlog → assigned → in progress → review → done.
+- **Context is durable.** Every task includes: objective, acceptance criteria, current blocker (if any), and next action. When an owner changes, the context transfers in writing.
+
+## Review and Shipping
+
+- **Nothing ships without review.** Code needs PR review. Design needs design review. Copy needs copy review. The owner names the reviewer, and the reviewer is accountable for the quality of their review.
+- **Review is a gate, not a discussion.** Reviewers approve, request specific changes, or escalate. Open-ended "what do you think?" loops are not reviews.
+- **Ship on green.** If CI passes and review is approved, the owner merges. No additional sign-off layers.
+
+## Disagreement and Escalation
+
+1. **First, disagree in writing.** Both parties write down their position and the evidence behind it. Oral disagreements are too cheap.
+2. **If unresolved in 24 hours, escalate.** The owner escalates to the nearest common manager with both positions documented.
+3. **The manager decides within 48 hours.** The manager picks a path, writes the rationale, and both parties commit.
+4. **No re-litigation for 30 days.** Once decided, the issue is closed. Revisit only with new evidence.
+
+## Communication
+
+- **Async-first.** Write it down before you say it out loud. Meetings are for decisions that cannot be made async, not for status updates.
+- **Default public.** Work in public channels and shared documents unless there is a specific confidentiality reason.
+- **No surprises.** If something is going wrong, the affected people hear it from us before they hear it from data.

+# Ways of Working
+
+## Version Control Discipline
+
+- **One task = one branch = one owner.**
+  Every issue gets its own branch. Branch names: `owner-identifier/short-description` (e.g., `ceo/ELF-3-hiring-plan`).
+- **No direct commits to `main`.** All changes go through a pull request.
+- **Rebase before merge.** Keep history linear and readable. Squash fixup commits.
+- **Commit messages explain why, not what.** The diff shows what changed; the message explains the reasoning.
+
+## Task Lifecycle
+
+```
+backlog → todo → in_progress → in_review → done
+   ↑___________|    ↑___________|
+```
+
+- **backlog:** Valid idea, not scheduled. Anyone can add items.
+- **todo:** Scheduled and ready. Has clear acceptance criteria.
+- **in_progress:** Checked out by an owner. Active work is happening.
+- **in_review:** Owner has handed off for review or approval.
+- **done:** Accepted and merged. No further action required.
+- **blocked:** Cannot proceed. Must name the blocker and who must act.
+
+## Standups
+
+We do not do live standups. We do **async written standups** in the issue thread or project channel.
+
+### Standup Template
+
+```
+**Yesterday:** What did I complete?
+**Today:** What am I working on?
+**Blocked:** What is in my way and who needs to act?
+```
+
+- Posted by 10:00 AM local time, every working day.
+- If you are blocked, you must name the owner of the unblock action.
+
+## Definition of Done
+
+A task is not done until **all** of the following are true:
+
+1. **Code is written and reviewed.** At least one approval from a qualified reviewer.
+2. **Tests pass.** CI is green. New code has relevant test coverage.
+3. **Documentation is updated.** If the change affects APIs, interfaces, or runbooks, the docs are updated in the same PR.
+4. **No secrets in plain text.** Credentials, tokens, and keys are never committed.
+5. **User-facing changes are validated.** QA or the owner has verified the change in a staging environment.
+6. **Rollback path is known.** For infra or deploy changes, the owner can articulate how to revert.
+7. **Handoff is clean.** If follow-up work exists, it is captured in a new issue with acceptance criteria and an owner.
+
+## Working Hours and Availability
+
+- **Async-first.** We do not require synchronous availability. Write things down.
+- **Response-time expectations:** 4 hours during business hours for blocking questions; 24 hours for non-blocking context.
+- **Deep work blocks.** Meetings and interruptions are the exception. Protect 2-4 hour blocks for focused work.

+# CLI Troubleshooting Guide
+
+Comprehensive troubleshooting guide for Hatch CLI issues.
+
+## Quick Diagnostics
+
+### Health Check
+
+First, verify the Hatch server is running and accessible:
+
+```bash
+# Check if server is responding
+curl -s http://localhost:8080/healthz
+
+# Expected output: ok
+
+# If using custom URL
+curl -s $HATCH_URL/healthz
+```
+
+### Version Check
+
+Verify you're using the correct version:
+
+```bash
+hatch version
+# Expected output: hatch v0.1.0
+
+# Check if binary is working
+hatch --help
+```
+
+### Connectivity Test
+
+Test network connectivity to the server:
+
+```bash
+# Test with verbose output
+curl -v http://localhost:8080/healthz
+
+# Test with specific timeout
+curl --connect-timeout 5 http://localhost:8080/healthz
+```
+
+## Common Error Messages
+
+### Connection Issues
+
+#### `Error: request failed: connection refused`
+
+**Cause:** The Hatch server is not running or not accessible.
+
+**Solutions:**
+
+1. Start the Hatch server:
+   ```bash
+   hatch serve
+   ```
+
+2. Check if the server is listening on the expected port:
+   ```bash
+   # Linux/macOS
+   netstat -tlnp | grep 8080
+   # or
+   lsof -i :8080
+   
+   # Windows
+   netstat -ano | findstr :8080
+   ```
+
+3. Verify the HATCH_URL environment variable:
+   ```bash
+   echo $HATCH_URL
+   # Should be http://localhost:8080 or your server URL
+   ```
+
+4. Check firewall settings:
+   ```bash
+   # Linux
+   sudo iptables -L -n | grep 8080
+   
+   # macOS
+   sudo pfctl -sr | grep 8080
+   ```
+
+#### `Error: request failed: dial tcp: lookup localhost: no such host`
+
+**Cause:** DNS resolution failure.
+
+**Solutions:**
+
+1. Use IP address instead of hostname:
+   ```bash
+   export HATCH_URL=http://127.0.0.1:8080
+   ```
+
+2. Check `/etc/hosts` file:
+   ```bash
+   grep localhost /etc/hosts
+   # Should contain: 127.0.0.1 localhost
+   ```
+
+#### `Error: request failed: context deadline exceeded`
+
+**Cause:** Request timeout.
+
+**Solutions:**
+
+1. Check server load:
+   ```bash
+   top -bn1 | grep hatch
+   ```
+
+2. Increase timeout (if using curl):
+   ```bash
+   curl --max-time 30 http://localhost:8080/healthz
+   ```
+
+3. Check network latency:
+   ```bash
+   ping localhost
+   ```
+
+### Authentication Errors
+
+#### `Error (HTTP 401): unauthorized`
+
+**Cause:** Authentication required but not provided.
+
+**Solutions:**
+
+1. Check if authentication is enabled:
+   ```bash
+   # Check server configuration
+   docker exec hatch-container env | grep AUTH
+   ```
+
+2. Provide authentication token:
+   ```bash
+   # For API requests
+   curl -H "Authorization: Bearer $HATCH_AUTH_TOKEN" http://localhost:8080/v1/endpoints
+   ```
+
+3. For development, disable authentication:
+   ```bash
+   # Start server without auth
+   HATCH_AUTH_ENABLED=false hatch serve
+   ```
+
+#### `Error (HTTP 403): forbidden`
+
+**Cause:** Insufficient permissions.
+
+**Solutions:**
+
+1. Check user roles and permissions
+2. Verify API token has required scopes
+3. Contact administrator for access
+
+### Request/Response Errors
+
+#### `Error (HTTP 400): bad request`
+
+**Cause:** Invalid request format.
+
+**Solutions:**
+
+1. Validate JSON format:
+   ```bash
+   echo '{"invalid":json}' | jq .
+   # Should show parse error
+   ```
+
+2. Check Content-Type header:
+   ```bash
+   curl -H "Content-Type: application/json" -d '{"valid":"json"}' ...
+   ```
+
+3. Verify request body size:
+   ```bash
+   # Check body size
+   echo -n '{"data":"..."}' | wc -c
+   ```
+
+#### `Error (HTTP 404): endpoint not found`
+
+**Cause:** Requested resource doesn't exist.
+
+**Solutions:**
+
+1. List available endpoints:
+   ```bash
+   curl http://localhost:8080/v1/endpoints
+   ```
+
+2. Check endpoint ID spelling:
+   ```bash
+   # Case-sensitive
+   hatch inspect MyEndpoint  # Wrong
+   hatch inspect myendpoint  # Correct
+   ```
+
+3. Verify endpoint has captured requests:
+   ```bash
+   hatch inspect myendpoint -limit 1
+   ```
+
+#### `Error (HTTP 413): payload too large`
+
+**Cause:** Request body exceeds size limit.
+
+**Solutions:**
+
+1. Reduce request body size
+2. Compress data before sending
+3. Split into smaller chunks
+
+#### `Error (HTTP 429): too many requests`
+
+**Cause:** Rate limiting.
+
+**Solutions:**
+
+1. Implement backoff:
+   ```bash
+   # Exponential backoff script
+   for i in {1..5}; do
+     sleep $((2**i))
+     hatch capture /api -body '{"retry":'$i'}' && break
+   done
+   ```
+
+2. Check rate limit headers:
+   ```bash
+   curl -I http://localhost:8080/v1/endpoints
+   # Look for X-RateLimit-* headers
+   ```
+
+### Data Errors
+
+#### `Error: invalid character '}' looking for beginning of value`
+
+**Cause:** Malformed JSON in request body.
+
+**Solutions:**
+
+1. Validate JSON:
+   ```bash
+   echo '{"key":"value"}' | jq .
+   ```
+
+2. Use proper escaping:
+   ```bash
+   # Bash
+   hatch capture /api -body '{"key":"value with \"quotes\""}'
+   
+   # Use file input
+   echo '{"key":"value"}' > request.json
+   hatch capture /api -body @request.json
+   ```
+
+3. Check for invisible characters:
+   ```bash
+   cat -A request.json
+   ```
+
+#### `Error: unexpected end of JSON input`
+
+**Cause:** Incomplete JSON response.
+
+**Solutions:**
+
+1. Check server logs for errors
+2. Verify network connection wasn't interrupted
+3. Try with smaller payload
+
+### Storage Errors
+
+#### `Error: database is locked`
+
+**Cause:** SQLite database contention.
+
+**Solutions:**
+
+1. Reduce concurrent operations
+2. Check for long-running transactions:
+   ```bash
+   # Monitor database locks
+   sqlite3 hatch.db "PRAGMA journal_mode=WAL;"
+   ```
+
+3. Consider using PostgreSQL for production
+
+#### `Error: no space left on device`
+
+**Cause:** Disk space exhausted.
+
+**Solutions:**
+
+1. Check disk space:
+   ```bash
+   df -h
+   du -sh /var/lib/hatch
+   ```
+
+2. Clean old data:
+   ```bash
+   # Remove requests older than 7 days
+   curl -X DELETE "http://localhost:8080/v1/endpoints/myendpoint/requests?older_than=7d"
+   ```
+
+3. Configure data retention:
+   ```bash
+   # Set retention policy
+   HATCH_RETENTION_DAYS=30 hatch serve
+   ```
+

+### Environment Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `HATCH_URL` | Hatch server URL | `http://localhost:8080` |
+
+### Global Options
+
+All commands support these flags:
+
+- `-h, --help`: Show help for the command
+- `version`: Print version information
+
+## Commands
+
+### `hatch serve`
+
+Start the Hatch server. This is the default command when no subcommand is specified.
+
+```bash
+# Start server on default port (8080)
+hatch serve
+
+# Start with custom port (use environment variable)
+PORT=9090 hatch serve
+```
+
+### `hatch capture <url>`
+
+Send a request to an endpoint and store it in Hatch.
+
+**Options:**
+
+- `-method METHOD`: HTTP method (default: `POST`)
+- `-body BODY`: Request body as JSON string
+- `-header KEY:VALUE`: Request header (repeatable)
+
+**Examples:**
+
+```bash
+# Capture a simple POST request
+hatch capture https://api.example.com/webhook
+
+# Capture with custom method and body
+hatch capture /my-endpoint -method PUT -body '{"status":"active"}'
+
+# Capture with headers
+hatch capture /api/events \
+  -header 'Content-Type:application/json' \
+  -header 'X-Webhook-Secret:abc123' \
+  -body '{"event":"user.created","data":{"id":123}}'
+```
+
+**URL Handling:**
+
+- Full URLs: `https://api.example.com/webhook` → endpoint ID derived from path
+- Relative paths: `/my-endpoint` → used directly as endpoint ID
+- Empty/`/` → defaults to `default` endpoint
+
+### `hatch inspect <endpoint>`
+
+Fetch captured requests as JSON.
+
+**Options:**
+
+- `-limit N`: Maximum number of requests to return (default: 100)
+
+**Examples:**
+
+```bash
+# Inspect all requests for an endpoint
+hatch inspect my-webhook
+
+# Limit to 10 most recent requests
+hatch inspect my-webhook -limit 10
+
+# Pretty-print JSON output
+hatch inspect my-webhook | jq .
+```
+
+**Output Format:**
+
+```json
+[
+  {
+    "id": "abc123",
+    "method": "POST",
+    "path": "/webhook",
+    "headers": {"Content-Type": "application/json"},
+    "body": "{\"event\":\"test\"}",
+    "status": 200,
+    "created_at": "2024-01-15T10:30:00Z"
+  }
+]
+```
+
+### `hatch search <endpoint>`
+
+Search captured traffic with query syntax.
+
+**Options:**
+
+- `-query QUERY`: Search query (required)
+- `-limit N`: Maximum number of results (default: 100)
+
+**Query Syntax:**
+
+| Query | Description |
+|-------|-------------|
+| `status:500` | Filter by HTTP status code |
+| `POST` | Filter by HTTP method |
+| `user.created` | Search in request body |
+| `Content-Type:application/json` | Filter by header |
+
+**Examples:**
+
+```bash
+# Find all 500 errors
+hatch search my-webhook -query 'status:500'
+
+# Find POST requests
+hatch search my-webhook -query 'POST'
+
+# Search for specific content in body
+hatch search my-webhook -query 'user.created'
+
+# Combine queries
+hatch search my-webhook -query 'status:500 POST'
+```
+
+### `hatch replay <request-id>`
+
+Replay a previously captured request to a target URL.
+
+**Options:**
+
+- `-endpoint ENDPOINT`: Source endpoint ID (required)
+- `-target URL`: Target URL to replay to (required)
+
+**Examples:**
+
+```bash
+# Replay a request
+hatch replay abc123 -endpoint my-webhook -target https://httpbin.org/post
+
+# Replay to a local development server
+hatch replay def456 -endpoint api-calls -target http://localhost:3000/webhook
+
+# Replay to a different environment
+hatch replay ghi789 -endpoint production-webhook -target https://staging.example.com/webhook
+```
+
+**Use Cases:**
+
+- Test webhook handlers in development
+- Reproduce bugs by replaying failed requests
+- Load testing with captured traffic patterns
+- Migrating traffic between environments
+
+### `hatch mock set <endpoint>`
+
+Configure mock responses for an endpoint.
+
+**Options:**
+
+- `-status CODE`: HTTP status code (default: 200)
+- `-body BODY`: Response body (string or base64)
+- `-header KEY:VALUE`: Response header (repeatable)
+
+**Examples:**
+
+```bash
+# Return 200 with JSON body
+hatch mock set my-webhook -status 200 -body '{"ok":true}'
+
+# Return error response
+hatch mock set my-webhook -status 500 -body '{"error":"internal error"}'
+
+# Return with custom headers
+hatch mock set my-webhook \
+  -status 200 \
+  -header 'X-RateLimit-Remaining:100' \
+  -header 'Cache-Control:no-cache'
+
+# Simulate rate limiting
+hatch mock set my-webhook \
+  -status 429 \
+  -header 'Retry-After:60' \
+  -body '{"error":"rate limited"}'
+```
+
+**Mock Behavior:**
+
+- Once configured, all requests to the endpoint return the mock response
+- Mock configuration persists until server restart or explicit reconfiguration
+- Original request capture continues alongside mock responses
+
+### `hatch doc generate <endpoint>`
+
+Generate OpenAPI 3.1 specification for an endpoint based on captured traffic.
+
+**Examples:**
+
+```bash
+# Generate OpenAPI spec
+hatch doc generate my-webhook
+
+# Save to file
+hatch doc generate my-webhook > openapi.json
+
+# Use with Swagger UI
+hatch doc generate my-webhook > openapi.json
+docker run -p 8081:8080 -e SWAGGER_JSON=/openapi.json -v $(pwd):/usr/share/nginx/html/swagger swaggerapi/swagger-ui
+```
+
+**Output:**
+
+Generates a complete OpenAPI 3.1 JSON specification including:
+
+- All captured request/response patterns
+- Schema definitions inferred from traffic
+- Example values from real requests
+- Endpoint documentation
+
+## Common Workflows
+
+### Development Environment Setup
+
+```bash
+# 1. Start Hatch server
+hatch serve &
+
+# 2. Capture incoming webhooks
+hatch capture /api/webhooks -method POST -body '{"test":true}'
+
+# 3. Inspect captured traffic
+hatch inspect api/webhooks
+
+# 4. Configure mock for frontend development
+hatch mock set api/webhooks -status 200 -body '{"status":"ok"}'
+```
+
+### Bug Reproduction
+
+```bash
+# 1. Find the failing request
+hatch search api/payments -query 'status:500'
+
+# 2. Get request details
+hatch inspect api/payments -limit 5
+
+# 3. Replay to debug
+hatch replay <request-id> -endpoint api/payments -target http://localhost:8080/debug
+```
+
+### API Documentation Generation
+
+```bash
+# 1. Capture representative traffic
+for endpoint in users posts comments; do
+  curl -X POST http://hatch:8080/$endpoint -d '{"sample":"data"}'
+done
+
+# 2. Generate OpenAPI specs
+hatch doc generate users > users-api.json
+hatch doc generate posts > posts-api.json
+
+# 3. Combine into single spec (using jq)
+jq -s '.[0] * .[1]' users-api.json posts-api.json > combined-api.json
+```
+
+### Load Testing Preparation
+
+```bash
+# 1. Capture production traffic patterns
+hatch inspect api/critical-path -limit 1000 > traffic.json
+
+# 2. Extract request patterns
+jq -r '.[] | "\(.method) \(.path)"' traffic.json | sort | uniq -c | sort -rn
+
+# 3. Replay to load testing tool
+hatch inspect api/critical-path -limit 100 | \
+  jq -r '.[] | "hatch replay \(.id) -endpoint api/critical-path -target https://loadtest.example.com"'
+```
+
+## Troubleshooting
+
+### Connection Issues
+
+**Problem:** `Error: request failed: connection refused`
+
+**Solution:** Ensure the Hatch server is running:
+
+```bash
+# Check if server is running
+curl http://localhost:8080/healthz
+
+# Start server if not running
+hatch serve
+```
+
+### Authentication Errors
+
+**Problem:** `Error (HTTP 401): unauthorized`
+
+**Solution:** Check if your Hatch instance requires authentication:
+
+```bash
+# For local development, ensure no auth is configured
+# For production, check HATCH_AUTH_TOKEN environment variable
+```
+
+### Request Not Found
+
+**Problem:** `Error (HTTP 404): endpoint not found`
+
+**Solution:** Verify the endpoint ID exists:
+
+```bash
+# List available endpoints
+curl http://localhost:8080/v1/endpoints
+
+# Check if endpoint has captured requests
+hatch inspect <endpoint-id> -limit 1
+```
+
+### JSON Parsing Errors
+
+**Problem:** `Error: invalid character '}' looking for beginning of value`
+
+**Solution:** Ensure request body is valid JSON:
+
+```bash
+# Use proper JSON escaping
+hatch capture /api -body '{"key":"value"}'
+
+# Or use a file
+hatch capture /api -body @request.json
+```
+
+### Permission Denied on Binary
+
+**Problem:** `Permission denied: ./hatch`
+
+**Solution:** Make the binary executable:
+
+```bash
+chmod +x hatch
+# Or move to a directory in PATH
+sudo mv hatch /usr/local/bin/
+```
+

+# Deploying the Hatch Homepage
+
+This document describes how the Hatch static homepage is deployed to hatch.surf.
+
+## Overview
+
+The homepage is deployed to two locations:
+
+1. **GitHub Pages** - Serves as a fallback and for GitHub-based discovery
+2. **hatch.surf server** - Primary deployment via Docker at https://hatch.surf
+
+## Architecture
+
+```
+site/
+├── index.html          # Main homepage
+├── style.css           # Stylesheet
+├── main.js             # JavaScript
+├── brand/              # Logo and favicon assets
+│   ├── favicon/
+│   └── og/
+├── blog/               # Blog directory
+├── Dockerfile          # nginx:alpine with static files baked in
+└── docker-compose.yml  # Local development
+```
+
+### Docker Deployment Flow
+
+```
+GitHub Push → GitHub Actions → Docker Build → SCP Image → Docker Run → Caddy (reverse proxy)
+```
+
+- Static files are **baked into the Docker image** during build
+- No host directory mounting (`/var/www`) required
+- Image is self-contained and portable
+
+## Server Setup
+
+### Prerequisites
+
+- Server: 46.250.250.48 (hatch.surf)
+- Docker installed
+- Caddy for reverse proxy and TLS
+- SSH access for deployment
+
+### Container Configuration
+
+- **Container name**: `hatch-homepage`
+- **Image**: `hatch-homepage:latest`
+- **Internal port**: 80 (nginx)
+- **Exposed port**: 127.0.0.1:3000 (proxied by Caddy)
+
+## Deployment
+
+### Automated (GitHub Actions)
+
+When changes are pushed to `main` branch affecting `site/` directory:
+
+1. **GitHub Pages** - Deployed automatically via GitHub Actions
+2. **Server** - Docker image built, uploaded, and deployed
+
+Required GitHub secrets:
+- `DEPLOY_HOST` - Server IP (46.250.250.48)
+- `DEPLOY_USER` - SSH username (root)
+- `DEPLOY_KEY` - SSH private key (base64 encoded)
+
+### Manual Deployment
+
+Use the deployment script:
+
+```bash
+# Dry run
+./scripts/deploy-site.sh --dry-run
+
+# Deploy
+DEPLOY_HOST=46.250.250.48 \
+DEPLOY_USER=root \
+DEPLOY_KEY=$(cat ~/.ssh/id_rsa | base64) \
+./scripts/deploy-site.sh
+```
+
+### Docker Commands (on server)
+
+```bash
+# Build image locally
+docker build -t hatch-homepage:latest ./site
+
+# Run container
+docker run -d \
+  --name hatch-homepage \
+  --restart unless-stopped \
+  -p 127.0.0.1:3000:80 \
+  hatch-homepage:latest
+
+# Check status
+docker ps | grep hatch-homepage
+
+# View logs
+docker logs hatch-homepage
+
+# Restart
+docker restart hatch-homepage
+```
+
+## Verification
+
+### Check Site Status
+
+```bash
+# HTTP redirect
+curl -s -o /dev/null -w "%{http_code}" http://hatch.surf/
+
+# HTTPS site
+curl -s -o /dev/null -w "%{http_code}" https://hatch.surf/
+
+# SSL certificate
+curl -v https://hatch.surf/ 2>&1 | grep -E "expire|issuer|subject"
+
+# Static assets
+curl -s -o /dev/null -w "%{http_code}" https://hatch.surf/style.css
+curl -s -o /dev/null -w "%{http_code}" https://hatch.surf/brand/og/default.png
+```
+
+### Browser Verification
+
+1. Visit https://hatch.surf
+2. Verify no browser warnings (SSL valid)
+3. Check that all assets load (CSS, images)
+4. Test responsive design
+
+## Troubleshooting
+
+### Container Issues
+
+```bash
+# Check container status
+docker ps -a | grep hatch-homepage
+
+# View container logs
+docker logs hatch-homepage
+
+# Enter container
+docker exec -it hatch-homepage sh
+
+# Check nginx config inside container
+docker exec hatch-homepage nginx -t
+```
+
+### Deployment Failures
+
+1. Check GitHub Actions logs
+2. Verify SSH access: `ssh root@46.250.250.48`
+3. Check Docker status: `docker ps`
+4. Check Caddy logs: `docker logs caddy`
+
+### Missing Assets
+
+1. Verify image contains files: `docker exec hatch-homepage ls -la /usr/share/nginx/html/`
+2. Check nginx access logs: `docker logs hatch-homepage`
+3. Ensure image is up to date: `docker pull hatch-homepage:latest`
+
+## Maintenance
+
+### Updating Content
+
+1. Edit files in `site/` directory
+2. Commit and push to `main` branch
+3. GitHub Actions will auto-deploy to both locations
+
+### SSL Renewal
+
+Caddy handles TLS automatically via Let's Encrypt. No manual renewal needed.
+
+### Backup
+
+The site is version-controlled in Git. Docker images are stored on the server.
+
+```bash
+# Backup Docker image
+docker save hatch-homepage:latest | gzip > hatch-homepage-backup.tar.gz
+
+# Restore
+docker load < hatch-homepage-backup.tar.gz
+```

+# Role Definition: First Software Engineer
+
+## Context
+
+El Foundation has established its charter, operating model, and engineering baseline. We are pre-product but have a clear technical direction. The first engineer will work directly with the CTO to build the initial product and set the engineering culture for every hire that follows.
+
+The engineering stack is **Go + SQLite + stdlib `net/http` + server-rendered HTML + SSE**, per [ADR-0001](https://github.com/elfoundation/hatch/blob/main/docs/adrs/0001-stack.md) and [ADR-0002](adrs/0002-hatch-detail-stack.md). The product is **Hatch**, a self-hostable HTTP request inspector + mocker that ships as a single static binary.
+
+## What They Will Own
+
+- **Product implementation.** Write the first lines of production code. Own features end-to-end from task assignment to merge.
+- **Technical foundation.** Help solidify the stack, tooling, and conventions. The code you write sets the standard.
+- **Quality bar.** Write tests, review PRs, and catch regressions before they reach users.
+- **Documentation.** If it is not written down, it does not exist. Document APIs, runbooks, and decisions as you go.
+- **Production reliability.** Once we have users, own on-call rotation with the CTO and ensure systems stay healthy.
+
+## Technical Skills Required
+
+### Must-Have
+
+- **Go** — comfortable with the language, idiomatic style, the `net/http` package, and the standard library. A `go test ./...` / `go vet ./...` workflow is the daily loop.
+- **HTTP fundamentals** — methods, status codes, headers, content negotiation, request/response lifecycle. SSE and chunked transfer are a plus.
+- **SQL and relational schema design** — schema design, query optimization, migration discipline. SQLite-specific knowledge is a plus but not required.
+- **Git and GitHub** — branching, rebasing, PR discipline, code review.
+- **Server-rendered HTML** — at least one templating system (`html/template`, Jinja, ERB, Handlebars). Comfort with progressive enhancement.
+- **Testing mindset** — writes tests as a default, not an afterthought. Knows when to reach for `httptest`, table tests, and in-memory fixtures.
+
+### Nice-to-Have
+
+- **`net/http` internals** — middleware, `http.Handler` composition, the `ServeMux` method-based routing added in Go 1.22.
+- **Docker / multi-stage builds** — comfortable debugging a `Dockerfile`, reading layer output, and shipping a `scratch`-based image.
+- **SQLite** — pragmas, indexes, JSON columns, the `modernc.org/sqlite` driver.
+- **Linux / single-binary services** — has run a Go service in production behind a reverse proxy (Caddy, nginx, Envoy).
+- **Devtools / API design taste** — has built or used webhook inspectors, request bin tools, or mocking tools. Empathy for the user is the job.
+- **TypeScript or another typed language** — transferable skill; nice but not a v0.1 requirement.
+- **Mongolian language or market context** — our early users are likely in Mongolia.
+
+### Explicitly Deferred (not required for v0.1)
+
+- Frontend frameworks (React, Next.js, Vue) — Hatch v0.1 is server-rendered. We may adopt one later; we are not starting there.
+- TypeScript / Node.js — the foundation is Go. TypeScript remains in the toolbox for tooling only.
+- Monorepo tooling (Turborepo, Nx) — single Go module, single binary, no need.
+- Tailwind / utility CSS — hand-written CSS is enough for v0.1 surfaces.
+
+## Attributes We Value
+
+- **Slope over intercept.** We care more about how fast you learn than what you already know. Go fluency is learnable; engineering judgment is not.
+- **Writes things down.** Async-first communication. Clear documentation. Decision records.
+- **Disagrees and commits.** Healthy dissent, then full commitment once a decision is made.
+- **Protects focus.** Ruthless prioritization. Says no to multitasking.
+- **Pulls for bad news.** Surfaces problems early. Does not hide blockers.
+- **Boring by default.** Reaches for the standard library before adding a dependency.
+
+## First 30-Day Priorities
+
+| Week | Focus | Deliverable |
+|---|---|---|
+| 1 | Onboard and ship the bootstrap | Merged `engineer/hatch-bootstrap` PR with `cmd/hatch` HTTP server, `Dockerfile`, CI green |
+| 2 | Ship Task 2 (SQLite storage layer) | Merged PR with `internal/storage/...`, migration runner, `:memory:` tests, schema in PR description |
+| 3 | First user-facing task (Capture, Inspect, or Mock) | At least one merged feature PR that exercises the full stack |
+| 4 | Document and refine | Updated [`local-dev.md`](local-dev.md) / [`hatch-architecture.md`](hatch-architecture.md) with real friction, first own-authored ADR |
+
+## Reporting
+
+- **Reports to:** CTO
+- **Peers:** None yet — you are the first IC
+- **Growth path:** Senior Engineer → Staff Engineer → Engineering Lead as the team scales
+
+## Compensation & Logistics
+
+- **Decision owner:** CEO (pending approval)
+- **Budget:** To be confirmed by CEO
+- **Location:** Remote / async-first
+- **Start date:** As soon as approved and hired
+
+## Recommendation
+
+**Hire a mid-level engineer with Go and HTTP-services experience.** They should have shipped a Go service to production and be comfortable with `net/http`, SQL, and Docker. A senior engineer would be ideal but may be overkill for our current stage and budget. A junior engineer would require too much hands-on guidance from the CTO, slowing both product velocity and hiring velocity.
+
+If a strong TypeScript engineer is the only available candidate, that's acceptable — the stack is small and the ramp is short — but Go experience is preferred.
+
+**Suggested title:** Software Engineer  
+**Suggested level:** Mid-level (2–5 years shipping production code)  
+**Priority:** High — we cannot build product without an engineer.

+Living document. The CTO sketches the component map; the engineer owns the details as the code lands.
+
+## One-sentence summary
+
+Hatch is a single Go binary that serves a server-rendered HTML UI and captures, inspects, and mocks HTTP requests against per-endpoint URLs, persisting everything in a single SQLite file.

+
+## Layer responsibilities
+
+### `cmd/hatch/main.go` — process entrypoint
+
+- Reads configuration (env: `PORT`).
+- Wires the `http.ServeMux` to the handler layer.
+- Starts `http.ListenAndServe`. Logs to stdout. Crashes on bind failure.
+
+### `internal/handler/` — HTTP layer
+
+- One file per route group: `capture.go`, `inspect.go`, `mock.go`, `sse.go`, `health.go`.
+- Handlers take a `store.Repository` (interface) — never a concrete type — so tests can swap in `:memory:` SQLite or a fake.
+- Handlers translate HTTP ↔ store calls. They do not contain business logic.
+- Server-rendered HTML lives next to the handler that renders it. Templates are `//go:embed`-ed at build time.
+
+### `internal/store/` — persistence layer
+
+- `schema.sql` is the canonical DDL. Applied idempotently on first start by `migrate.go`.
+- `models.go` defines the Go structs (`Endpoint`, `Request`).
+- `repository.go` defines the `Repository` interface. The HTTP layer depends on this interface, not on the SQLite implementation.
+- `sqlite_repo.go` is the concrete implementation. Uses `modernc.org/sqlite` (pure Go, no CGO).
+- `db.go` opens the database file (or `:memory:` for tests), configures pragmas, returns a `*sql.DB`.
+
+### SSE hub (in `internal/handler/sse.go`)
+
+- A goroutine per connected browser, holding an `http.Flusher`.
+- A `chan store.Request` that capture handlers publish to.
+- The hub fans out new requests to all subscribers for the relevant endpoint.
+- No external broker. No Redis. No pubsub library. A `chan` and a `map[endpointID][]chan` is the entire implementation for v0.1.
+
+## Request lifecycle
+
+1. **Capture** — a webhook hits `/{endpoint-id}` (any method). The capture handler:
+   - Reads method, path, query, headers, body.
+   - Calls `store.AppendRequest(ctx, request)`.
+   - Publishes the new request to the SSE hub.
+   - Looks up the endpoint's mock response and returns it.
+2. **Inspect** — a browser hits `GET /e/{endpoint-id}`. The inspect handler:
+   - Calls `store.ListRequests(ctx, endpointID, limit=100)`.
+   - Renders an HTML page with the request list (newest first).
+   - The page includes a small vanilla-JS `EventSource` client that subscribes to `/e/{endpoint-id}/events`.
+3. **Live update** — the SSE handler holds the connection open, flushes each new request as a `data:` frame, and the browser appends it to the list.
+4. **Mock** — `PUT /e/{endpoint-id}/mock` accepts `{status, headers, body}` and updates the endpoint. Subsequent captures to that endpoint return the configured response.
+
+## Data model
+
+Two tables. That's it for v0.1.
+

+
+## Boundaries
+
+- **No authentication.** v0.1 is single-user, self-hosted. If you can reach the port, you can read and write. See [v0.1-scope.md](../adrs/v0-1-scope.md).
+- **No multi-tenancy.** One SQLite file, one process, one operator. Cloud is v0.2+.
+- **No external services.** No Redis, no Postgres, no S3. If the binary needs to phone home, the design is wrong.
+- **No client-side framework.** The browser gets HTML and a 50-line `events.js`. Anything more is out of scope for v0.1.
+
+## Performance budget
+
+v0.1 is sized for a single developer self-hosting on a $5 VPS:
+
+- **Cold start:** under 100 ms (Go binary + SQLite open).
+- **Capture latency:** under 5 ms p99 on the happy path (no auth, no remote calls).
+- **SSE fan-out:** one goroutine per connected browser, no message broker.
+- **Database size:** comfortable to 100k requests per endpoint. Retention policy is out of scope for v0.1.
+
+If a real workload breaks these, we measure first, then add complexity.
+
+## Future seams (do not build now)
+
+These are deliberate extension points, not planned features. The v0.1 implementation should not block them but also should not build them.
+
+- **Pluggable storage** — the `Repository` interface is the seam. A Postgres or S3-backed implementation would slot in without handler changes.
+- **Pluggable auth** — a middleware in front of the mux. The v0.1 mux is exposed without auth, which is the right v0.1 default.
+- **Replay / forwarding** — the `Request` struct has the full request. Replay is "read from store, write back out." Forwarding is the same plus a destination.
+- **Multi-tenant cloud** — partitioning by `endpoint_id` is already first-class. A `tenant_id` column is a v0.2 change.
+
+When the v0.1 design cannot accommodate one of these without a rewrite, we have under-designed. When the v0.1 design has built one of these speculatively, we have over-designed.

+# Local Development
+
+This is the day-to-day workflow for working on Hatch. If something here disagrees with what you actually observe, update this doc — the docs are a living artifact.
+
+## Prerequisites
+
+- **Go 1.25 or newer** — `go version` should report 1.25+. Install from <https://go.dev/doc/install> or via your package manager.
+- **Docker** (optional but recommended) — only required if you want to exercise the `docker compose` flow.
+- **`curl`** — for smoke tests against the running server.
+- **`sqlite3`** CLI (optional) — for poking at the database file directly. Not required for the normal workflow.
+
+## Clone and Build
+
+```bash
+git clone https://github.com/elfoundation/hatch.git
+cd hatch
+go mod download
+```
+
+## Run the Server
+
+The fastest path is `go run`:
+
+```bash
+go run ./cmd/hatch
+# hatch starting on :8080
+```
+
+In another terminal:
+
+```bash
+curl -fsS http://localhost:8080/healthz
+# ok
+```
+
+The server reads its port from the `PORT` environment variable and defaults to `:8080`.
+
+```bash
+PORT=9090 go run ./cmd/hatch
+# hatch starting on :9090
+```
+
+## Run the Tests
+
+```bash
+go test ./...
+```
+
+This runs the full test suite, including the smoke test that boots the HTTP server in-process and hits `/healthz`. Add `-v` for verbose output, `-race` for the race detector.
+
+```bash
+go test ./... -v -race
+```
+
+## Vet and Format
+
+```bash
+go vet ./...
+gofmt -l .
+```
+
+CI runs `go vet ./...`. `gofmt -l .` lists any unformatted files (no output means everything is formatted). Run `gofmt -w .` to fix formatting in place.
+
+## Build a Static Binary
+
+```bash
+CGO_ENABLED=0 go build -ldflags="-s -w" -o bin/hatch ./cmd/hatch
+ls -lh bin/hatch
+```
+
+The resulting binary is fully static, has no libc dependency, and runs on any Linux x86_64 with the same kernel.
+
+## Docker Compose
+
+For the full local stack (Hatch + optional Caddy reverse proxy for TLS):
+
+```bash
+# Plain HTTP — Hatch only
+docker compose up --build
+
+# With Caddy (HTTPS, self-signed in dev)
+docker compose --profile with-caddy up --build
+```
+
+The compose file reads `.env` for `HATCH_HOSTNAME`. Copy `.env.example` to `.env` and adjust:
+
+```bash
+cp .env.example .env
+# Edit HATCH_HOSTNAME=localhost  (or your real domain)
+```
+
+## Where Things Live
+
+| Path | Purpose |
+|---|---|
+| `cmd/hatch/` | Server entrypoint. `main.go` wires up `http.ServeMux`, `main_test.go` is the smoke test. |
+| `internal/handler/` | HTTP handlers (Capture, Inspect, Mock). One file per route group. |
+| `internal/store/` | Storage layer. `schema.sql` is the canonical DDL, `sqlite_repo.go` is the SQLite-backed implementation of the `Repository` interface. |
+| `docs/engineering/` | Engineering standards and architecture docs. |
+| `docs/adrs/` | Architecture Decision Records. |
+| `Dockerfile` | Multi-stage build: `golang:1.25-alpine` → `scratch` with the static binary. |
+| `docker-compose.yml` | Local stack: Hatch on `:8080`, optional Caddy sidecar for TLS. |
+| `.env.example` | Documented environment variables. |
+| `hatch.db` (gitignored) | SQLite database file. Created on first start in the working directory. |
+
+## SQLite Tips
+
+The database is a single file. By default it lives at `./hatch.db` in the process working directory.
+
+```bash
+# Inspect the schema
+sqlite3 hatch.db '.schema'
+
+# List endpoints
+sqlite3 hatch.db 'SELECT * FROM endpoints;'
+
+# Reset (destructive)
+rm hatch.db
+# Schema is recreated on next start
+```
+
+For tests that need a clean database, use the `:memory:` SQLite database — see `internal/store/sqlite_repo_test.go` for the pattern. Do not point tests at the on-disk database file.
+
+## Common Tasks
+
+| Task | Command |
+|---|---|
+| Run the server | `go run ./cmd/hatch` |
+| Run all tests | `go test ./...` |
+| Run a single test | `go test ./internal/handler -run TestCapture -v` |
+| Vet | `go vet ./...` |
+| Format | `gofmt -w .` |
+| Build a binary | `CGO_ENABLED=0 go build -o bin/hatch ./cmd/hatch` |
+| Docker stack | `docker compose up --build` |
+| Reset the database | `rm hatch.db` |
+
+## Troubleshooting
+
+**`go: command not found`** — Install Go 1.25+ and ensure `$HOME/go/bin` (or wherever `go install` puts binaries) is on your `PATH`.
+
+**`bind: address already in use`** — Another process is on `:8080`. Either stop it or run with `PORT=9090 go run ./cmd/hatch`.
+
+**Tests fail with `database is locked`** — A previous test process left a handle. Look for stray `hatch` processes (`ps aux | grep hatch`) and kill them. Tests should use `:memory:` databases and not share the on-disk file.
+
+**Docker build fails on `go.sum`** — Run `go mod tidy` locally, commit `go.sum`, rebuild. The Dockerfile copies `go.sum` before `go mod download` for reproducible builds.
+
+**`CGO_ENABLED` warning during `go build`** — The static-binary build sets `CGO_ENABLED=0` explicitly. If you forget, the binary will dynamically link libc and break the "single static binary" promise.

+# Technology Stack
+
+## Overview
+
+These choices were made by the CTO on 2026-06-22 to align the engineering foundation with [ADR-0001](https://github.com/elfoundation/hatch/blob/main/docs/adrs/0001-stack.md) and the Hatch product thesis. They are reversible within a day for local development, but would require migration effort once production data exists. All choices default to boring, well-supported technology over novelty.
+
+The stack is chosen so that a single `docker compose up` (or one binary on a VPS) is the entire product — no separate database server, no build step, no auth process. This is the v0.1 distribution promise; if a choice makes that promise harder, it has to earn its place.
+
+## Backend & Data
+
+| Layer | Choice | Rationale |
+|---|---|---|
+| Language | Go 1.25 | Single static binary, fast iteration, strong stdlib for HTTP and SQL. "One command on a VPS" requires a self-contained binary. |
+| HTTP server | stdlib `net/http` (Go 1.22+ method-based routing) | No router dependency for a v0.1 surface. `go-chi/chi` is allowed where middleware is genuinely needed (SSE). |
+| Database | SQLite via `modernc.org/sqlite` | Pure-Go driver keeps the "no CGO" promise. Survives restarts, zero-ops, single file you can `cp` to back up. |
+| Migrations | Hand-rolled runner that applies `internal/storage/schema.sql` on first start, idempotently | Premature tooling is paid complexity. One SQL file, one `CREATE TABLE IF NOT EXISTS`, ship it. |
+| Templates | stdlib `html/template` | Server-rendered HTML with auto-escaping. No JS build step, no hydration cost, no SPA complexity for what is fundamentally a server-driven UI. |
+| Live updates | Server-Sent Events (SSE) on `net/http` | One-way push from server to browser, no WebSocket framing, plays nicely with the `html/template` render path. |
+
+## Frontend
+
+| Layer | Choice | Rationale |
+|---|---|---|
+| UI architecture | Server-rendered HTML + a little vanilla JS | The UI is a small request list with one live update. JS is loaded only where it earns its bandwidth (the SSE client). No bundler. |
+| CSS | Hand-written CSS in `internal/handler/assets/` | Tailwind and friends add a build step we explicitly do not want in v0.1. A small `style.css` is enough for the surfaces we ship. |
+| Client JS | Vanilla JS (no framework, no transpiler) | One `events.js` for the SSE subscription. If we ever need more, we will earn a toolchain. |
+
+## Packaging & Distribution
+
+| Layer | Choice | Rationale |
+|---|---|---|
+| Container | Multi-stage `Dockerfile` (golang:1.25 → scratch) | Produces an 8–10 MB static binary image. No runtime, no shell, no package manager on the final image. |
+| Local dev | `docker compose` with optional Caddy sidecar | `docker compose up` is the one-command demo. Caddy handles TLS for the demo host and stays out of the way for plain HTTP. |
+| Demo TLS | Caddy (auto-issues Let's Encrypt in prod, self-signed in dev) | Hands-off TLS, sane defaults, plays well with the static-binary promise. |
+| Config | Env vars (read with `os.Getenv`) | Twelve-factor. No YAML/JSON config files for v0.1. Defaults documented in `.env.example`. |
+
+## Tooling
+
+| Layer | Choice | Rationale |
+|---|---|---|
+| Build | `go build` (with `CGO_ENABLED=0` for the final binary) | No Makefile needed for the common path. |
+| Tests | stdlib `testing` + `net/http/httptest` | No assertion library until pain demands one. |
+| Vet / lint | `go vet ./...` in CI | Stdlib tooling, no `golangci-lint` config to maintain. |
+| CI | GitHub Actions (`.github/workflows/ci.yml`) | `go vet` → `go test` → `docker build` → smoke-test the running image. |
+| Markdown lint | `markdownlint-cli2` (non-blocking) | Editorial consistency, not a gate. |
+| Module path | `github.com/elfoundation/hatch` | Matches the GitHub org. Easy to change before any external consumer depends on it. |
+
+## Principles
+
+These are stack-agnostic and outlive any choice in the tables above. They are the cultural defaults; the tables are the implementation.
+
+- **Server-rendered by default.** Reach for client JS or a SPA only when the component genuinely needs state, effects, or live updates.
+- **Pure logic in `internal/`, I/O in adapters.** Business logic does not call `http.*` or `database/sql` directly. Storage and HTTP are replaced with interfaces in tests.
+- **Store timestamps as UTC.** Render in local time only at the edge.
+- **Single static binary, single file database.** If a dependency breaks that, justify it.
+- **Observability before optimization.** Measure before fixing. No tuning without metrics.
+- **Idempotency.** Operations should be safe to retry. Migrations, request capture, and SSE reconnect are all idempotent.
+- **Boring technology.** A new dependency must earn its place. If stdlib covers it, stdlib wins.
+
+## Open Decisions
+
+| Decision | Status | Owner | Blocker |
+|---|---|---|---|
+| Router (stdlib `net/http` vs. `go-chi/chi`) | Provisional — start with stdlib, adopt chi if SSE middleware pain demands it | CTO | Live SSE implementation in v0.1 Inspect task |
+| Structured logging library | Open — `slog` (stdlib) likely sufficient | CTO | First production deploy |
+| Tracing / metrics | Open | CTO | Hosting decision |
+| Hosting target (Fly, single VPS, k8s?) | Open | CEO | Need product requirements and traffic estimates |

+# Community-listening list — Week 1
+
+**Owner:** Social Media Manager
+**Reporter:** Head of Marketing
+**Source issue:** [ELF-51](/ELF/issues/ELF-51)
+**Source plan:** [30-Day Marketing Plan — Hatch v0.1 Launch](/ELF/issues/ELF-49#document-plan) (§3 channel mix, §7 "CEO needs to decide")
+**Period:** week of 2026-06-22 → 2026-06-28 (pre-launch)
+**Goal:** be a *helpful* presence on the channels the audience already uses, not a spam account.
+
+## How to use this list
+
+1. **Helpful, not spammy.** Reply to the question, not the thread. Only mention Hatch if it is the actual answer to what was asked.
+2. **No marketing copy.** No taglines, no "check us out", no `@hatch_http` signature. If a reply wouldn't be useful to a stranger, it doesn't ship.
+3. **One ask per reply.** If we can answer a question without a link, answer without a link. A link is only OK if the person is clearly choosing between tools.
+4. **Read the room.** Skip threads where the original poster has been silent for >24h, or where a moderator is actively pruning self-promotion. Don't argue with a thread that's already decided.
+5. **No customer commitments.** If anyone asks for a feature, a date, a price, or an SLA, route to the [Head of Marketing](/ELF/agents/headofmarketing) and the [CEO](/ELF/agents/ceo) per the brand-voice guide.
+
+## Week 1 — 10 threads (HN primary; Reddit expansion in a follow-up child issue)
+
+Each row is one thread, with the wedge, the specific engagement approach, and a no-go line.
+
+### 1. Ngrok Alternatives (Ask HN, Feb 2022)
+- **Link:** https://news.ycombinator.com/item?id=30443747
+- **Why it matters:** the canonical "what do I use instead of ngrok" thread; 244 points, 97 comments, still active. Audience is exactly the dev who would land on Hatch's landing page.
+- **Engagement plan:** answer the *unanswered* variants: "if you specifically need to debug a webhook (not tunnel to localhost), a self-hosted request inspector + mocker is a different tool. We built one — happy to share what worked and what didn't, but I won't drop a link in a 2022 thread."
+- **What *not* to do:** post a one-line "use our tool" with a link. That gets flagged and we lose the account on day one.
+
+### 2. Pico: An open-source Ngrok alternative built for production traffic (Show HN, May 2024)
+- **Link:** https://news.ycombinator.com/item?id=40355744
+- **Why it matters:** a Show HN from a peer tool, 244 points, 55 comments. The thread is full of production-traffic questions (TLS, auth, retention, observability).
+- **Engagement plan:** reply to top comment about "I just need to see what landed in this POST" with a *focused* recommendation: "for the inspect-and-mock half, a single Go binary + SQLite has been enough for our 100k-request/endpoint workload. happy to share schema notes if useful."
+- **What *not* to do:** don't link the repo from this comment. The thread is about Pico, not about us. We earn credibility by helping, not by linking.
+
+### 3. Tunnelmole, an ngrok alternative (open source) (Show HN, Mar 2024)
+- **Link:** https://news.ycombinator.com/item?id=39754786
+- **Why it matters:** 206 points, 83 comments, the "tunnel + logger" thread.
+- **Engagement plan:** answer the "I just need to log POSTs to a URL" question. Confirm that the tunnel-half (ngrok, tunnelmole) and the inspect-half (requestbin, hatch) are *different jobs* and we built the inspect-half. If asked for the link, share in a child reply, not a top-level comment.
+- **What *not* to do:** compare ourselves to Tunnelmole in a top-level comment. We're solving a different problem; saying so in a top-level reads as a drive-by.
+
+### 4. Portr – open-source ngrok alternative designed for teams (Show HN, Apr 2024)
+- **Link:** https://news.ycombinator.com/item?id=39913197
+- **Why it matters:** 172 points, 24 comments. Strong fit for the "team" / "compliance" sub-thread.
+- **Engagement plan:** reply to the "what about a self-hosted option that doesn't phone home" comment. Acknowledge Portr, note that *for the webhook-inspect case* a different tool (requestbin, hookdeck) is the right move, and offer to share what we shipped.
+- **What *not* to do:** don't paste the GitHub link. Let them ask.
+
+### 5. Show HN: Webhix – Self-hosted webhook.site alternative in a single Go binary (Show HN, Jun 2026)
+- **Link:** https://news.ycombinator.com/item?id=48460403
+- **Why it matters:** a direct Show HN for the same wedge, posted last week. Low traffic (3 points) which makes the thread easy to be a good citizen in.
+- **Engagement plan:** leave a useful technical comment. Specifically: ask about the SSE/EventSource story (do they push new requests to a live tab?), share what we learned about a `chan store.Request` + `map[endpointID][]chan` fan-out. If the conversation is going well, mention in a *reply* that we built the same wedge.
+- **What *not* to do:** don't write "we built the same thing, here's ours" as a top-level comment. The author is the OP; show up as a peer, not a competitor.
+
+### 6. Show HN: Hookaido – "Caddy for Webhooks" (Show HN, Feb 2026)
+- **Link:** https://news.ycombinator.com/item?id=46958502
+- **Why it matters:** a different framing ("Caddy for X"). Useful to read for the audience's mental model.
+- **Engagement plan:** engage on the routing/forwarding story. Note that Hatch's v0.1 deliberately omits forwarding (it captures and returns a configured mock), and ask whether anyone in the thread has needed forwarding on day one.
+- **What *not* to do:** don't claim we're "Caddy for inspecting" or otherwise co-opt the Caddy brand. That's marketing-speak, not what this thread is.
+
+### 7. Show HN: Whook – Free self hosted alternative to hookdeck, webhook.site (Show HN, Jan 2026)
+- **Link:** https://news.ycombinator.com/item?id=46840462
+- **Why it matters:** direct competitor framing, 1 point, low traffic. Audience is already self-hosting-curious.
+- **Engagement plan:** reply to the OP with one concrete technical question (their stack, persistence model), and one *helpful* observation about the size of the self-hosted-webhook-inspector space.
+- **What *not* to do:** don't list Hatch as an alternative in the same reply. The thread is the OP's thread; making it about us is a brand-voice failure.
+
+### 8. Show HN: Requestbin.com – A modern take on the old RequestBin (Show HN, Aug 2019)
+- **Link:** https://news.ycombinator.com/item?id=20758684
+- **Why it matters:** old but still shows up in searches; useful for SEO backlinks and the "long tail" reader. 18 points, 10 comments.
+- **Engagement plan:** add a *self-hosted* alternative to the "alternatives" sub-thread, not the top-level. "If you specifically need a self-hosted version (compliance / data-residency), a Go binary + SQLite has worked for us." No link in the comment.
+- **What *not* to do:** don't try to rewrite a 2019 thread. Most readers are looking for the OP's tool, not a rehash.
+
+### 9. Show HN: Webhook Tester – RequestBin-style webhooks inbox built on Cloudflare (Show HN, Dec 2025)
+- **Link:** https://news.ycombinator.com/item?id=46273261
+- **Why it matters:** a hosted alternative on Cloudflare. Audience is the *opposite* of Hatch's wedge (they want hosted; we win on self-hosted).
+- **Engagement plan:** reply to "what about self-hosted?" comment with the trade-off (Cloudflare Workers is faster to deploy; self-hosting on a $5 VPS is faster to audit and survives Cloudflare outages). Acknowledge the OP built something good.
+- **What *not* to do:** don't position Hatch as "better than Cloudflare". That's a fight we don't win on HN.
+
+### 10. Show HN: RePlaya – self-hosted browser session replay with live tailing (Show HN, Jun 2026)
+- **Link:** https://news.ycombinator.com/item?id=48373482
+- **Why it matters:** 50 points, 8 comments, posted last week. Not a webhook tool, but in the *self-hosted dev tool* wedge and the "live tailing" pattern maps to Hatch's SSE feed.
+- **Engagement plan:** engage on the "live tailing" pattern specifically. Note that the same pattern (a `chan` per endpoint + a fan-out map) covers a request log; ask what the OP learned about backpressure under load.
+- **What *not* to do:** don't pitch Hatch. The thread is about session replay; forcing the connection is a brand-voice failure.
+
+## Reddit expansion (follow-up child issue)
+
+HN is enough for week 1. Reddit's anti-bot wall blocked the listing endpoint from our environment, so the Reddit half of this list is filed as a [follow-up child issue](/ELF/issues/ELF-55) (when it exists; assigned to Social Media Manager for week 2). The target subreddits, per the [30-day plan §3](/ELF/issues/ELF-49#document-plan):
+
+- `r/selfhosted` — primary Reddit wedge. Look for: "requestbin alternative self-hosted", "webhook debugger", "self-hosted ngrok alternative".
+- `r/golang` — for the "I built a Go tool" Show-style posts.
+- `r/devops` — for the "debug webhook in staging" angle.
+- `r/programming`, `r/webdev` — for generalist threads; engage carefully, the self-promotion tolerance is lower.
+
+## Metrics we'll track on this list (recorded on the issue after the week closes)
+
+For each of the 10 threads:
+- Did we reply? (yes / no / skipped)
+- Reply depth (top-level vs. sub-thread)
+- Did we mention Hatch? (yes / no — and if yes, was the mention in the *first* reply or only after a follow-up question)
+- Net karma delta on the account (if any; mostly defensive)
+- Any reply from a thread participant that wants a follow-up (route to [Head of Marketing](/ELF/agents/headofmarketing))
+
+The success metric is not "how many clicks did we get". The success metric is "are we a credible presence on HN after week 1". We'll measure that by whether replies from us land above the threshold on week-2+ threads.
+
+## Out of scope for this list
+
+- Cross-posting on LinkedIn / Mastodon — explicitly out of scope per [ELF-49 §3](/ELF/issues/ELF-49#document-plan).

+# Hatch Examples
+
+Real-world examples and integration guides for using Hatch.
+
+## Examples Index
+
+| Example | Description | Use Case |
+|---------|-------------|----------|
+| [Webhook Integration](webhook-integration.md) | Comprehensive webhook capture, testing, and debugging | Payment processors, GitHub, Slack, API integrations |
+
+## Quick Start Examples
+
+### Capture Your First Request
+
+```bash
+# Start Hatch server
+hatch serve &
+
+# Capture a request
+curl -X POST http://localhost:8080/my-endpoint \
+  -H "Content-Type: application/json" \
+  -d '{"event":"test","data":{"id":123}}'
+
+# View captured requests
+hatch inspect my-endpoint
+```
+
+### Mock API for Development
+
+```bash
+# Configure mock response
+hatch mock set api/users \
+  -status 200 \
+  -header "Content-Type:application/json" \
+  -body '[{"id":1,"name":"John Doe"}]'
+
+# Test your frontend
+curl http://localhost:8080/api/users
+```
+
+### Debug Failed Webhooks
+
+```bash
+# Find errors
+hatch search webhooks -query "status:500"
+
+# Replay to debug
+hatch replay <request-id> \
+  -endpoint webhooks \
+  -target http://localhost:3000/debug
+```
+
+## Integration Guides
+
+### Stripe Webhooks
+
+See [Webhook Integration - Stripe Example](webhook-integration.md#example-1-stripe-webhook-testing)
+
+### GitHub Webhooks
+
+See [Webhook Integration - GitHub Example](webhook-integration.md#example-2-github-webhook-debugging)
+
+### Slack Integration
+
+See [Webhook Integration - Slack Example](webhook-integration.md#example-3-slack-integration-testing)
+
+## Use Cases
+
+### 1. Development Environment
+
+Use Hatch as a local mock server for frontend development.
+
+```bash
+# Configure mocks for your API
+hatch mock set api/users -status 200 -body '[]'
+hatch mock set api/auth -status 200 -body '{"token":"mock-token"}'
+
+# Frontend code uses http://localhost:8080 as API base
+```
+
+### 2. Testing & QA
+
+Capture production traffic patterns and replay them in testing.
+
+```bash
+# Capture traffic
+hatch inspect api/critical-path -limit 1000 > traffic.json
+
+# Replay in test environment
+cat traffic.json | jq -r '.[].id' | while read id; do
+  hatch replay "$id" -endpoint api/critical-path -target http://staging:8080
+done
+```
+
+### 3. API Documentation
+
+Generate OpenAPI specs from real traffic.
+
+```bash
+# Capture representative traffic
+hatch capture /api/users -method GET
+hatch capture /api/users -method POST -body '{"name":"test"}'
+
+# Generate documentation
+hatch doc generate api/users > users-api.json
+```
+
+### 4. Load Testing
+
+Replay captured traffic for load testing.
+
+```bash
+# Capture production patterns
+hatch inspect api/critical-path -limit 1000 > load-test-traffic.json
+
+# Create load test script
+cat > load-test.sh << 'EOF'
+#!/bin/bash
+for i in {1..100}; do
+  hatch inspect api/critical-path -limit 10 | \
+    jq -r '.[] | "hatch replay \(.id) -endpoint api/critical-path -target http://loadtest:8080"' | \
+    bash &
+done
+wait
+EOF
+chmod +x load-test.sh
+```
+
+## Best Practices
+
+1. **Use descriptive endpoint names**
+   ```bash
+   # Good
+   hatch capture /webhooks/stripe-payments
+   hatch capture /api/v2/users
+   
+   # Bad
+   hatch capture /a
+   hatch capture /test
+   ```
+
+2. **Include relevant headers**
+   ```bash
+   hatch capture /webhooks/github \
+     -header 'X-GitHub-Event:push' \
+     -header 'X-Hub-Signature:sha1=abc123'
+   ```
+
+3. **Organize by environment**
+   ```bash
+   # Development
+   hatch mock set dev/api/users -status 200 -body '[]'
+   
+   # Staging
+   hatch mock set staging/api/users -status 200 -body '[{"id":1}]'
+   ```
+
+4. **Use search for debugging**
+   ```bash
+   # Find all errors
+   hatch search api/webhooks -query 'status:500'
+   
+   # Find specific events
+   hatch search webhooks/stripe -query 'payment_intent'
+   ```

+
+### Multi-Environment Setup
+
+```bash
+# Development environment
+hatch mock set payments/webhook \
+  -status 200 \
+  -body '{"status":"received"}'
+
+# Staging environment
+hatch capture payments/webhook \
+  -body '{"type":"payment.completed","amount":1000,"currency":"USD"}'
+
+# Replay to different environments
+hatch replay <payment-id> \
+  -endpoint payments/webhook \
+  -target http://localhost:8080/payments/webhook  # Local

+  -body '{"status":"failed","error":"insufficient_funds"}'
+
+# Simulate network timeout (use with caution)
+hatch mock set payments/webhook \
+  -status 504 \
+  -body '{"error":"gateway_timeout"}'
+```
+
+## Example 5: API Documentation Generation
+
+Generate OpenAPI documentation from real traffic patterns.
+
+### Capture API Traffic
+
+```bash
+# Capture various endpoints
+hatch capture /api/users -method GET
+hatch capture /api/users -method POST -body '{"name":"John Doe"}'
+hatch capture /api/users/123 -method GET
+hatch capture /api/users/123 -method PUT -body '{"name":"Jane Doe"}'
+hatch capture /api/posts -method GET
+hatch capture /api/posts -method POST -body '{"title":"Hello World"}'
+```
+
+### Generate Documentation
+
+```bash
+# Generate OpenAPI specs for each endpoint
+hatch doc generate api/users > users-api.json
+hatch doc generate api/posts > posts-api.json
+
+# Combine into single spec
+jq -s '.[0] * .[1]' users-api.json posts-api.json > combined-api.json
+
+# Serve with Swagger UI
+docker run -p 8081:8080 \
+  -e SWAGGER_JSON=/openapi.json \
+  -v $(pwd):/usr/share/nginx/html/swagger \
+  swaggerapi/swagger-ui
+```
+
+## Example 6: Load Testing with Real Traffic
+
+Capture and replay production traffic for load testing.
+
+### Capture Production Patterns
+
+```bash
+# Capture high-traffic endpoint
+hatch capture /api/critical-path -limit 1000
+
+# Export traffic patterns
+hatch inspect api/critical-path -limit 1000 > traffic-patterns.json
+```
+
+### Analyze Traffic
+
+```bash
+# Analyze request distribution
+jq -r '.[] | "\(.method) \(.path)"' traffic-patterns.json | \
+  sort | uniq -c | sort -rn
+
+# Find slow requests (if timing data available)
+jq '.[] | select(.duration > 1000)' traffic-patterns.json
+
+# Identify error patterns
+jq '.[] | select(.status >= 400)' traffic-patterns.json
+```
+
+### Replay for Load Testing
+
+```bash
+# Create load test script
+cat > load-test.sh << 'EOF'
+#!/bin/bash
+ENDPOINT="api/critical-path"
+TARGET="https://loadtest.example.com"
+REQUESTS=$(hatch inspect $ENDPOINT -limit 100)
+
+echo "$REQUESTS" | jq -r '.[] | .id' | while read -r id; do
+  echo "Replaying request $id"
+  hatch replay "$id" -endpoint "$ENDPOINT" -target "$TARGET"
+  sleep 0.1  # Rate limiting
+done
+EOF
+
+chmod +x load-test.sh
+./load-test.sh
+```
+
+## Example 7: Mock Server for Frontend Development
+
+Set up a comprehensive mock server for frontend development.
+
+### Create Mock Endpoints
+
+```bash
+# User API mock
+hatch mock set api/users \
+  -status 200 \
+  -header 'Content-Type:application/json' \
+  -body '[
+    {"id":1,"name":"John Doe","email":"john@example.com"},
+    {"id":2,"name":"Jane Smith","email":"jane@example.com"}
+  ]'
+
+# Authentication mock
+hatch mock set api/auth \
+  -status 200 \
+  -header 'Content-Type:application/json' \
+  -body '{"token":"mock-jwt-token-123","expires_in":3600}'
+
+# Error responses
+hatch mock set api/errors \
+  -status 401 \
+  -header 'Content-Type:application/json' \
+  -body '{"error":"unauthorized","message":"Invalid credentials"}'
+```
+
+### Frontend Integration
+
+```javascript
+// Frontend code using mock API
+const API_BASE = 'http://localhost:8080';
+
+// Fetch users
+const response = await fetch(`${API_BASE}/api/users`);
+const users = await response.json();
+
+// Login
+const loginResponse = await fetch(`${API_BASE}/api/auth`, {
+  method: 'POST',
+  headers: { 'Content-Type': 'application/json' },
+  body: JSON.stringify({ email: 'user@example.com', password: 'pass' })
+});
+```
+
+## Best Practices
+
+### 1. Use Descriptive Endpoint Names
+
+```bash
+# Good
+hatch capture /webhooks/stripe-payments
+hatch capture /api/v2/users
+
+# Bad
+hatch capture /a
+hatch capture /test
+```
+
+### 2. Include Relevant Headers
+
+```bash
+# Capture with all relevant headers
+hatch capture /webhooks/github \
+  -header 'X-GitHub-Event:push' \
+  -header 'X-Hub-Signature:sha1=abc123' \
+  -header 'Content-Type:application/json'
+```
+
+### 3. Organize by Environment
+
+```bash
+# Development
+hatch mock set dev/api/users -status 200 -body '[]'
+
+# Staging
+hatch mock set staging/api/users -status 200 -body '[{"id":1}]'
+```
+
+### 4. Use Search for Debugging
+
+```bash
+# Find all errors
+hatch search api/webhooks -query 'status:500'
+
+# Find specific event types
+hatch search webhooks/stripe -query 'payment_intent'
+```
+
+### 5. Document Your Mocks
+
+```bash
+# Add comments to mock configuration
+hatch mock set api/users \
+  -status 200 \
+  -header 'X-Mock-Description:Returns list of test users'
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Connection refused**: Ensure Hatch server is running (`hatch serve`)
+2. **Endpoint not found**: Check endpoint ID with `curl http://localhost:8080/v1/endpoints`
+3. **Request not captured**: Verify request format and headers
+4. **Mock not working**: Check if mock is configured for the correct endpoint
+
+### Debug Mode
+
+```bash
+# Enable debug logging
+DEBUG=true hatch serve
+
+# Check server logs
+docker logs -f hatch-container
+```
+
+### Performance Issues
+
+```bash
+# Limit concurrent connections
+hatch inspect api/heavy-endpoint -limit 10
+
+# Use pagination for large datasets
+hatch inspect api/large-dataset -limit 50
+```
